Hello there!
First of all, the Google Play Services Extension works fine. I mean, log-in, leaderboard and achievements.
1. My problem is that I can't see the OAuth 2.0 authorisation window (with checkboxes etc.). I set up my OAuth 2.0 IDs with 4 scopes (like in guide), game already in release, the Services log-in is instantaneous when I launch the game.
In previous GPServicesExtension OAuth 2.0 works as it should (as Google wants).
2. The second problem is most likely not related to GMS2...
Google Play Services / Licensing / OAuth 2 / AIP
