Code Accidental Deletion

I have seen another comment on this review page talking about this same design flaw. I would feel a lot more comfortable if I knew that accidentally swiping away an authentication code is not possible. Please fix this in the next update, there is no reason to keep this ‘feature’

Great app when it works

I open the app and try to get my codes but its just stuck on the splash screen after face ID step. Looks like i will need to switch but not sure how as i cant get in the app💀

Figured it out its because im screen sharing (i am a mobile developer and always cast to my laptop)

Update review

Search function was not working. Now it is back to normal. I can easily search the proper account. Very helpful when you have dozens of accounts.
