I set up Google Play Services on my mobile game so that I could add a leaderboard.
When I open up the app on mobile, debugging over USB, I successfully log in to Play Services and am able to view the leaderboards.
But, when I published my app on the Google Play Store I do not successfully log in to Play Services and I cannot view the leaderboards.
I'm completely new to this and would really appreciate some help. Please let me know if you have any ideas!
Edit: I'm using this plugin to connect Google Play Services https://github.com/cgisca/PGSGP
