PR Author Checklist

• [x] I linked the correct issue in the ### Fixed Issues section above
• [x] I wrote clear testing steps that cover the changes made in this PR
  • [x] I added steps for local testing in the Tests section
  • [x] I added steps for the expected offline behavior in the Offline steps section
  • [x] I added steps for Staging and/or Production testing in the QA steps section
  • [x] I added steps to cover failure scenarios (i.e. verify an input displays the correct error message if the entered data is not correct)
  • [x] 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)
  • [x] 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).
• [x] I included screenshots or videos for tests on all platforms
• [x] I ran the tests on all platforms & verified they passed on:
  • [x] Android: Native
  • [x] Android: mWeb Chrome
  • [x] iOS: Native
  • [x] iOS: mWeb Safari
  • [x] MacOS: Chrome / Safari
  • [x] MacOS: Desktop
• [x] 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)
• [x] I verified there are no new alerts related to the canBeMissing param for useOnyx
• [x] I followed proper code patterns (see Reviewing the code)
  • [x] 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)
  • [x] I verified that comments were added to code that is not self explanatory

    • [x] 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:
  • [x] I verified all numbers, amounts, dates and phone numbers shown in the product are using the localization methods
  • [x] 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.
  • [x] 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.

• [x] 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
• [x] I verified that if a function's arguments changed that all usages have also been updated correctly
• [x] If any new file was added I verified that:
  • [x] 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
• [x] If a new CSS style is added I verified that:
  • [x] A similar style doesn't already exist
  • [x] The style can't be created with an existing StyleUtils function (i.e. StyleUtils.getBackgroundAndBorderStyle(themeColors.componentBG))
• [x] If new assets were added or existing ones were modified, I verified that:
  • [x] The assets are optimized and compressed (for SVG files, run npm run compress-svg)
  • [x] The assets load correctly across all supported platforms.
• [x] 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.
• [x] 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)
• [x] 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.
• [x] 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.
• [x] If the PR modifies the form input styles:
  • [x] I verified that all the inputs inside a form are aligned with each other.
  • [x] I added Design label so the design team can review the changes.
• [x] 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.
• [x] I added unit tests for any new feature or bug fix in this PR to help automatically prevent regressions in this user flow.

BUG: List does not scroll to the report preview after tracking distance, only the carousel does

https://github.com/user-attachments/assets/96642f5b-4bfd-430f-933f-cf033dff30af

[dominictb]

BUG: Carousel scroll does not include left margin:

1. Drag n drop 3 receipts into Scan tab
2. The carousel scrolls to the 3 latest expenses but the left margin is missing

Should be like this:

BUG: Transaction previews are missing rounded border and have different heights (should all have the same height)

https://github.com/user-attachments/assets/0293a1dd-e0a7-4dc7-842d-7a9fd1b4a1ad

This is possibly not related to the PR change but I cannot reproduce it on main, only in this branch.

I think it does. It's an existing bug, but we're trying to make the new expenses more apparent. It is not apparent if the carousel is hidden in the chat list.

Are you suggesting we should broaden the scope here and fix it? Because the bug is not at all directly in the scope of this issue.

@FitseTLT Let me break it down:

1. An expense report already has 2 expenses
2. Drag n drop 3 more receipts
3. Carousel scrolls to the right but is missing left margin

I am not even sure if that's not an expected behavior. I mean we could easily give some viewOffset to the scroll, like in the vid below which has a viewOffset of 10. But are u sure that is better? @dominictb

[dominictb]

Yes that's better

Done

BUG:

This is a weird one.

1. Go to a workspace chat
2. Create a manual expense
3. Carousel does not scroll
4. Go to the expense report, try to delete some expenses (the number of expenses is still < 10) (from 0:51 in the recording)
5. Create a manual expense
6. Carousel scrolls but stops in the middle
