GoogleApiClient: Games.API and Auth.GOOGLE_SIGN_IN_API not working together

I have a working application for signing in with a google account.

I'm building my client like this

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN)
.requestEmail()
.requestProfile()
.requestIdToken(getString(R.string.server_client_id))
.build();

GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.addConnectionCallbacks(this)
.build();


Now I decided to add the
Games.API
resulting in the following client:

GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this)
.addApi(Games.API)
.addScope(Games.SCOPE_GAMES)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.addConnectionCallbacks(this)
.build();


However when I try to connect the client

googleApiClient.connect();


I get the following exception:

java.lang.IllegalStateException: Cannot use SIGN_IN_MODE_REQUIRED with GOOGLE_SIGN_IN_API. Use connect(SIGN_IN_MODE_OPTIONAL) instead.


So I read the exception and modified my connection call to

googleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);


So now I don't get any more exceptions but the client never gets connected for some reason. Any ideas why the client does not connect now?

The code worked perfectly fine on any other device than my testing device. After reinstalling Google Play on my testing device it also worked! I don't know what caused the issues but the reinstall fixed it.
