App is buggy and it deletes all the codes
it was such a pain to recover all the codes and go back to Google Authy. There is saying if it isn't broken then don't fix it. Use titanium and back it up.
Still, your codes won't get deleted and lost if you backup them. That's the whole point of using a different 2FA app like andOTP. Enable and backup. Easy right?
It's not vague. I spent 5 hours recovering all my accounts. I tried it twice. First time andOTP got cleared. Second time I was able to backup it and then I re-open the app to see all the codes gone but then I tried to restore and that didn't work also. So I switched back to Google Authy.
