Please do search the forum.
Possible reasons.

1. Firebase url may not present in your google-services.json(90%)
2. may not add sha1 key in fingerprint region
3. app name may be mis matched between firebase and your app

Thank you!!! the error was that it was not putting the packname of the app’s firabase, it was blank, when I put it in kodular it worked !! Thank you so much
