I am getting ready to publish my game on Android and implementing Google Play Services with Xamarin.
I have couple questions for Leaderboards implementation.
My goal is to implement both Achievements and Leaderboards in-game, without the Google overlay.
I upload a score to leaderboard and when I try to load the leaderboard scores with "await GamesClass.Leaderboards.LoadTopScoresAsync", in the response I get Status about reconnect required. If I try to load scores of a leaderboard where I haven't uploaded a score I get Status = OK with no scores, as expected.
Even if I try to show the leaderboard with a score through the built-in overlay intent, the overlay shows up for a second and goes away.
If I try to show overlay for empty leaderboard the empty leaderboard shows up and stays there until I manually go back.
Automatic Signing-in, unlocking and reading Achievements is working properly.
Achievements and Leaderboards are created in Developer Console and it says Ready For Testing but nothing has been published so far.
I appreciate any help, tip or link that I can use to finalize the implementation!
