Hey @nyenloop,

Thank you for reporting this issue. It appears similar to previously reported cases found here on GitHub and here on Google Groups.

The issue seems to stem from excessive sign-ins and, based on the title of your issue, it also occurs on React Native. This suggests that the root cause is likely from the native SDK, not the Flutter one.

Could you try waiting a bit, using another phone number, and then see if the issue persists?

The exception is QuotaExceeded, this means you have hit the limit for the IP address. You might be able to whitelist your phone number which you can do in the Firebase console. Although, you will still have to wait until the temporary restriction is lifted by the Firebase server. (i.e. whitelist your phone number and wait a day for the ban to be lifted). This isn't something to be fixed on FlutterFire so I am closing it out.
