google play games authentication with firebase not working on Unity - firebase

Question

I've followed the official instructions https://firebase.google.com/docs/auth/unity/play-games to configure the google play games authentication with firebase on Unity, but unfortunately it isn't working. I think the authentication process is failing when it tries to request the auth ID from play games.
Here the log from logcat:
