If the app says your code is wrong even though you've typed it correctly, it's almost always because an account on your device has been suspended.
Suspensions can apply to the device, not just the account, so a new code won't let you in while one is active — even if you're signing in with a different email address.
If you haven't appealed yet, submit a Suspension Appeal Form. You can appeal once, and you have 7 days to do it.
If you've already appealed, wait for us to come back to you. Codes will start working once the suspension is resolved.
If you're sure no account on your device has been suspended, Report an issue and we'll take a look.
