DeveloperError Exception of type 'Google.GoogleSignIn+SignInException', googleplaystore, unity, google login? - unity3d

Question

I have weird behaviour for my SignInWithGoogle.
I have everything set up for QAuth, SSH, WebClieng etc.
And when I sent a build to my phone directly. All work fine. I can SignIn, LogIn etc.
But when I made an aab build and uploaded it to google console and downloaded it from GooglePlay, as a tester, I received DeveloperError Exception of type 'Google.GoogleSignIn+SignInException.
Is there maybe something I need to change on QAuth to fix that?
public class SignInWithGoogle : MonoBehaviour
{
public static string slaveUserEmail;
public static string slaveUserPassword;
string webClientId = "536446807232-vh3olku8c637olltqlge92p17qmsqmtl.apps.googleusercontent.com";
private GoogleSignInConfiguration configuration;
FirebaseAuth _auth;
bool _initialized = false;
void Awake()
{
FireBaseInit.OnInitialized += OnFirebaseInit;
configuration = new GoogleSignInConfiguration
{
WebClientId = webClientId,
RequestIdToken = true
};
}
public void OnFirebaseInit()
{
if (_initialized) return;
_auth = FirebaseAuth.DefaultInstance;
_initialized = true;
Debug.Log("GoogleAuth Initialized");
}
public void OnSignIn()
{
Debug.Log("Calling SignIn");
GoogleSignIn.Configuration = configuration;
GoogleSignIn.Configuration.UseGameSignIn = false;
GoogleSignIn.Configuration.RequestIdToken = true;
var signInCompleted = new TaskCompletionSource<FirebaseUser>();
Debug.Log("SignInInit");
try
{
GoogleSignIn.DefaultInstance.SignIn().ContinueWith(task =>
{
if (task.IsFaulted)
{
using (IEnumerator<Exception> enumerator =
task.Exception.InnerExceptions.GetEnumerator())
{
if (enumerator.MoveNext())
{
GoogleSignIn.SignInException error =
(GoogleSignIn.SignInException)enumerator.Current;
Debug.Log("Got Error: " + error.Status + " " + error.Message);
}
else
{
Debug.Log("Got Unexpected Exception?!?" + task.Exception);
}
}
}
else if (task.IsCanceled)
{
Debug.Log("Canceled");
}
else
{
Debug.Log("Welcome in Google: " + task.Result.DisplayName + "!");
Debug.Log("GEt Ceds");
Credential credential = GoogleAuthProvider.GetCredential(task.Result.IdToken, null);
Debug.Log("Creds added");
Debug.Log("Firebase Log In try!");
FirebaseAuth.DefaultInstance.SignInWithCredentialAsync(credential).ContinueWith(authTask =>
{
if (authTask.IsCanceled)
{
Debug.Log("Auth Canceld");
signInCompleted.SetCanceled();
}
else if (authTask.IsFaulted)
{
Debug.Log("Auth Faulted");
signInCompleted.SetException(authTask.Exception);
}
else
{
Debug.Log("Auth Coplited");
signInCompleted.SetResult(((Task<FirebaseUser>)authTask).Result);
}
});
}
});
}
catch (Exception ex)
{
Debug.Log(ex.Message);
}
}
