Details to reproduce: Put a name to a shared tab, no special letters: “Xyz’s Gift” (without quotes, tried to drop the single apostrophe too), select few contacts (tried 1 to 4 contacts), then get a failure. Also tried resetting cache and force closing the application.
I have the same issue (same steps to reproduce and the same error message).
I’ve tried contacting support but it’s a somewhat slow/clunky process going through the triage process (‘have you uninstalled the app’, ‘have you tried a different internet connection’) via the in-app chat that doesn’t notify me of new messages.
I’m on 5.19.0 of the Android app on a Pixel 5 on Android 13 with the latest Play and security updates.
I can share my Monzo account number with Monzo staff via DM if that helps.
