Making this external but also asked the agencies to look into this one closely https://expensify.slack.com/archives/C05LX9D6E07/p1716902910273389

@kirillzyusko has got some good investigation going on in the thread

[kavimuru]

Retested in https://42725.pr-testing.expensify.com/r (web / mweb) and in the android adhoc build https://ad-hoc-expensify-cash.s3.amazonaws.com/android/42725/index.html . It was a pass. Tester does not have access to iOS ad hoc build

Merged revert PR #42725 to fix this for now, to unblock deploy

This issue has not been updated in over 15 days. @akinwale, @strepanier03, @chiragsalian eroding to Monthly issue.

P.S. Is everyone reading this sure this is really a near-term priority? Be brave: if you disagree, go ahead and close it out. If someone disagrees, they'll reopen it, and if they don't: one less thing to do!

I think this can be closed now
