I m trying to migrate google sign in from one account to another in my android app. I have add the package name and sha1 key into new account and then also added the"google-services.json" file. But every time i m running it, it shows me "failed message=12500".
I have tried everything, looked at all the solutions everywhere.
When i use the old account and old "google-services.json" file it works but as soon i tried to migrate to new account it doesn't work. The crazy thing about this is that i m using other services as well like firebase notification, phone authentication and remote config they all work perfectly fine in the new account, but not google sign.
