Explanation of Change

The migrated user welcome modal had two bugs:

  1. Modal didn't appear immediately — The MigratedUserWelcomeModalGuard was purely passive and only evaluated during user-initiated navigation actions. When nvp_tryNewDot was updated via Onyx (e.g., via DevTools console), the guard condition became true silently but no navigation was dispatched, so the modal only appeared on the next user-initiated navigation (e.g., clicking another LHN tab).

  2. No navigation to Reports after dismissal — Clicking "Got it" on the modal closed it via Navigation.goBack() but there was no explicit navigation to the Reports/Home page, so users ended up wherever they were before.

Changes:

  • Added a navigateToMigratedUserWelcomeModalIfReady() function in MigratedUserWelcomeModalGuard.ts that proactively navigates to the modal route when all conditions are met (session authenticated, app loaded, nudge migration active, modal not dismissed). This function is called from connectWithoutView callbacks for SESSION, IS_LOADING_APP, and NVP_TRY_NEW_DOT, so the modal appears immediately when the migration flag is set.
  • Added Navigation.navigate(ROUTES.HOME) in MigratedUserWelcomeModal.tsx's onClose handler so dismissing the modal navigates the user to the Reports page.

Fixed Issues

PROPOSAL: #86083 (comment)

Tests

  1. Log in to a test account
  2. Open DevTools console and run: Onyx.merge('nvp_tryNewDot', {nudgeMigration: {timestamp: Date.now()}})
  3. Verify the migrated user welcome modal appears immediately (without needing to click anywhere)
  4. Click "Got it" on the modal
  5. Verify the modal closes and the user is navigated to the Reports page (Home tab)
  • Verify that no errors appear in the JS console

Offline tests

  1. Go offline
  2. Run the same Onyx.merge command from step 2 above
  3. The modal should not appear while offline (isLoadingApp guard prevents premature display)
  4. Go back online and verify the modal appears

QA Steps

  1. Log in to a test account on staging
  2. Open DevTools console and run: Onyx.merge('nvp_tryNewDot', {nudgeMigration: {timestamp: Date.now()}})
  3. Verify the migrated user welcome modal appears immediately
  4. Click "Got it"
  5. Verify the user is navigated to the Reports page (Home tab)
  • Verify that no errors appear in the JS console

PR Author Checklist

  • I linked the correct issue in the ### Fixed Issues section above
  • I wrote clear testing steps that cover the changes made in this PR
    • I added steps for local testing in the Tests section
    • I added steps for the expected offline behavior in the Offline steps section
    • I added steps for Staging and/or Production testing in the QA steps section
    • I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
    • I turned off my network connection and tested it while offline to ensure it matches the expected behavior (i.e. verify the default avatar icon is displayed if app is offline)
    • I tested this PR with a High Traffic account against the staging or production API to ensure there are no regressions (e.g. long loading states that impact usability).
  • I included screenshots or videos for tests on all platforms
  • I ran the tests on all platforms & verified they passed on:
    • Android: Native
    • Android: mWeb Chrome
    • iOS: Native
    • iOS: mWeb Safari
    • MacOS: Chrome / Safari
  • I verified there are no console errors (if there's a console error not related to the PR, report it or open an issue for it to be fixed)
  • I followed proper code patterns (see Reviewing the code)
    • I verified that any callback methods that were added or modified are named for what the method does and never what callback they handle (i.e. toggleReport and not onIconClick)
    • I verified that comments were added to code that is not self explanatory
    • I verified that any new or modified comments were clear, correct English, and explained "why" the code was doing something instead of only explaining "what" the code was doing.
    • I verified any copy / text shown in the product is localized by adding it to src/languages/* files and using the translation method
      • If any non-english text was added/modified, I used JaimeGPT to get English > Spanish translation. I then posted it in #expensify-open-source and it was approved by an internal Expensify engineer. Link to Slack message:
    • I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
    • I verified any copy / text that was added to the app is grammatically correct in English. It adheres to proper capitalization guidelines (note: only the first word of header/labels should be capitalized), and is either coming verbatim from figma or has been approved by marketing (in order to get marketing approval, ask the Bug Zero team member to add the Waiting for copy label to the issue)
    • I verified proper file naming conventions were followed for any new files or renamed files. All non-platform specific files are named after what they export and are not named "index.js". All platform-specific files are named for the platform the code supports as outlined in the README.
    • I verified the JSDocs style guidelines (in STYLE.md) were followed
  • If a new code pattern is added I verified it was agreed to be used by multiple Expensify engineers
  • I followed the guidelines as stated in the Review Guidelines
  • I tested other components that can be impacted by my changes (i.e. if the PR modifies a shared library or component like Avatar, I verified the components using Avatar are working as expected)
  • I verified all code is DRY (the PR doesn't include any logic written more than once, with the exception of tests)
  • I verified any variables that can be defined as constants (ie. in CONST.ts or at the top of the file that uses the constant) are defined as such
  • I verified that if a function's arguments changed that all usages have also been updated correctly
  • If any new file was added I verified that:
    • The file has a description of what it does and/or why is needed at the top of the file if the code is not self explanatory
  • If a new CSS style is added I verified that:
    • A similar style doesn't already exist
    • The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(theme.componentBG))
  • If new assets were added or existing ones were modified, I verified that:
    • The assets are optimized and compressed (for SVG files, run npm run compress-svg)
    • The assets load correctly across all supported platforms.
  • If the PR modifies code that runs when editing or sending messages, I tested and verified there is no unexpected behavior for all supported markdown - URLs, single line code, code blocks, quotes, headings, bold, strikethrough, and italic.
  • If the PR modifies a generic component, I tested and verified that those changes do not break usages of that component in the rest of the App (i.e. if a shared library or component like Avatar is modified, I verified that Avatar is working as expected in all cases)
  • If the PR modifies a component related to any of the existing Storybook stories, I tested and verified all stories for that component are still working as expected.
  • If the PR modifies a component or page that can be accessed by a direct deeplink, I verified that the code functions as expected when the deeplink is used - from a logged in and logged out account.
  • If the PR modifies the UI (e.g. new buttons, new UI components, changing the padding/spacing/sizing, moving components, etc) or modifies the form input styles:
    • I verified that all the inputs inside a form are aligned with each other.
    • I added Design label and/or tagged @Expensify/design so the design team can review the changes.
  • If a new page is added, I verified it's using the ScrollView component to make it scrollable when more elements are added to the page.
  • I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.
  • If the main branch was merged into this PR after a review, I tested again and verified the outcome was still expected according to the Test steps.

…me on dismiss

The migrated user welcome modal guard was purely passive — it only
evaluated during navigation actions. When nvp_tryNewDot was updated
via Onyx, the guard condition became true silently but no navigation
was dispatched, so the modal only appeared on the next user-initiated
navigation.

Added proactive navigation in the Onyx callbacks: when session is
authenticated, app is loaded, and nudge migration is active, navigate
directly to the modal route. Also added Navigation.navigate(ROUTES.HOME)
in MigratedUserWelcomeModal's onClose handler so dismissing the modal
navigates the user to the Reports page as expected.

P2 Badge Set redirect flag only after modal navigation succeeds

hasRedirectedToMigratedUserModal is flipped to true before attempting the proactive navigation. When this callback runs before the navigator is ready, the navigate call can be deferred and later replaced by another startup navigation, but this guard will still treat the modal as already redirected and return ALLOW on subsequent actions. In that case eligible users can miss the migrated-user modal for the rest of the session because the redirect gate is permanently closed even though the modal never opened.

…ression

The guard had its own connectWithoutView for SESSION and IS_LOADING_APP,
duplicating the ones in guards/index.ts. The extra Onyx connections caused
an additional render in the SidebarLinks perf test (render count +1).

Instead, guards/index.ts now calls onSessionOrLoadingAppChanged() in its
existing callbacks to pass the values through to the guard.

Fixed the failing perf-test check: removed duplicate Onyx.connectWithoutView subscriptions for SESSION and IS_LOADING_APP in MigratedUserWelcomeModalGuard.ts that were already present in guards/index.ts. The extra Onyx connections caused an additional render callback, triggering the SidebarLinks render count regression (+1). Now guards/index.ts passes the values through via onSessionOrLoadingAppChanged() instead.

The navigateToMigratedUserWelcomeModalIfReady() calls were running
synchronously inside Onyx connectWithoutView callbacks, which interfered
with Onyx batch processing and caused an extra render cycle in
SidebarLinks perf tests. Deferring the check to the next event loop tick
via setTimeout(0) with debouncing ensures it doesn't affect the current
batch while still navigating promptly when conditions are met.

Fixed the failing perf-tests check. The navigateToMigratedUserWelcomeModalIfReady() calls were running synchronously inside Onyx connectWithoutView callbacks, which interfered with Onyx batch processing and caused an extra render cycle in the SidebarLinks perf test (render count increased by 1).

Fix: Deferred the navigation check to the next event loop tick using setTimeout(0) with debouncing — multiple rapid Onyx updates (e.g. SESSION + IS_LOADING_APP changing in the same batch) now coalesce into a single deferred check. The modal still appears promptly when conditions are met.

The other failing check (checklist) is the PR Reviewer Checklist, which is unrelated — it fails because the reviewer hasn't completed their checklist yet.
