Answer 1

in my case it happened when I was using the emulator, and tried to log in with a real number. You can use test phone numbers instead Firebase auth docs

Note; Phone number sign-in is only available for use on real devices and the web. To test your authentication flow on device emulators, please see Testing.

addition: Sometimes wipe emulator data helps.
