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
  • MacOS: Desktop
• 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 verified there are no new alerts related to the canBeMissing param for useOnyx
• 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 verified the translation was requested/reviewed 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 approved by marketing by adding the Waiting for Copy label for a copy review on the original GH to get the correct copy.
  • 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.js 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(themeColors.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 form input styles:
  • I verified that all the inputs inside a form are aligned with each other.
  • I added Design label 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.

This seems to make sense to me. We shouldn't lose/change your chat position in another tab if you simply open a new one and click into another chat. 👍

[rojiphil]

@FitseTLT I'm not sure if I am missing a step here, but I'm unable to reproduce the issue in staging.
Are you able to reproduce?

Yes @rojiphil you are indeed missing steps. First you should test it on different tabs not windows and you should be on the expense report not policy chat just like the OP. I know the title mislead you I have updated it. Thx

[rojiphil]

Ah.. Now I get it.. Thanks @FitseTLT for pointing it out.
Meanwhile, I notice that we still have issues. Please have a look at the following test video.

@FitseTLT Sorry for the delay here. Can you please merge again? Will check with the latest.

  • For Class Components, any internal methods passed to components event handlers are bound to this properly so there are no scoping issues (i.e. for onClick={this.submit} the method this.submit should be bound to this in the constructor)

[rojiphil]

Thanks @FitseTLT.

@arosiclair Changes LGTM and works well too.
Over to you. Thanks

[arosiclair]

Why move this code from the NavigationRoot to the AppNavigator? Does this fix not work without this change?

[FitseTLT]

Yes useNavigationState should be used under a NavigationContainer.

[arosiclair]

Previously we were using the NavigationContainer's onStateChange. Can we just keep using that to update the current reportID? I think adding additional hooks here might trigger more full app re-renders and impact performance.

[FitseTLT]

What about the memoization of AuthScreens

App/src/libs/Navigation/AppNavigator/AuthScreens.tsx

Line 703 in 6a6e6a4

const AuthScreensMemoized = memo(AuthScreens, () => true);

wouldn't that immediately stop re-renders and performance degradation as it is the direct child of AppNavigator

App/src/libs/Navigation/AppNavigator/index.tsx

Line 29 in 6a6e6a4

<AuthScreens />

the disadvantage of using the onStateChange callback is that it is too slow to be called an causes a flickering problem #56523

[arosiclair]

Can you show a video of that flickering problem in this context?

[FitseTLT]

Here is the flickering.

2025-12-01.19-42-22.mp4

But when removing setTimeout delay here

App/src/libs/Navigation/NavigationRoot.tsx

Lines 252 to 255 in 1f7efee

	// Performance optimization to avoid context consumers to delay first render
	setTimeout(() => {
	currentReportIDValue?.updateCurrentReportID(state);

the flickering becomes almost unrecognizable

2025-12-01.19-44-00.mp4

But working on the pr they claimed it was a little jumpy here and considered removing the delay as not sufficient I am afraid that we would cause a regression if we only remove the delay.

[arosiclair]

Here is the flickering.
https://github.com/user-attachments/assets/0b7cf110-6160-42d1-8f78-2bc1ce2f8c88

I don't really see an issue 😕. Can you push changes to use onStateChange and @rojiphil can you retest for any flickering issues?

[arosiclair]

bump @FitseTLT and @rojiphil

[FitseTLT]

Agree with you. Implemented. @rojiphil U can continue 👍

[rojiphil]

LGTM from the flickering perspective.
