authentication - Firebase and new Google Sign-In on Android

Question

I'm trying to add support for the new Google Sign-in announced as part of Play services 8.3.0. I successfully configured the project and I'm getting a token from the GoogleApiClient, but Firebase is returning an Invalid Credentials error when calling ref.authWithOAuthToken("google", token)

Google+ sign-in is working but that requires a separate permission which is a pain when developing for Marshmallow. Firebase android tutorial has a Google+ sign-in sample and my feeling is that they dont' have support for the new Google Sign-In yet.

Has anyone tried the new Google Sign-In in connection with Firebase and got it to work?
