Messenger CRITICAL BUG - PRIVACY CONCERN: messages not editing or deleting

DETAILS: A message in an E2EE group chat got stuck on Sending after edit (tried reopening app, restarting phone, clearing cache, logging back in, turning on unrestricted battery use), and when I Deleted for Everyone, it didn't delete for others. Then someone else in the group confirmed they were encountering the same issue on their own messages.

If you're encountering this issue, I suggest reporting to Messenger so more likely fixed (supposedly).

This is what happens when developers use AI to code.
