• Check if you have linked firebase with Google Play, follow: https://firebase.google.com/docs/android/integrate-play-games.
• Check if the OAuth client under Play Games Services → Setup and management → Configuration → Credentials contains the same fingerprint as the release fingerprint you posted in your firebase project under Project Settings → Your Apps → android → SHA certificate fingerprints.

            android:name="com.google.android.gms.games.APP_ID"
            android:value="@string/app_id" />

        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
