My app is running without problem, and it seems to connect to google play - it asks to login and shows google play logo with logo from api console, but functions like “read leaderboard integer” or “show platform specific achievements screen” always fail.
Game services on Play developer console are published and properly set-up. My mail is also added to testing section. I don’t know if this would help in any way but I’m using my app in shipping mode.
Now when I deployed game on iOS these buttons function but since I haven’t configured iOS leaderboards and etc. I cannot verify them working.
Feel free to comment and thanks in advance
