title: Leader board only getting displayed for testers
body: <p>I have published a simple game with google game api.
  All the code written have been taken from :
  <a href="https://developers.google.com/games/services/android/leaderboards#updating_the_players_score" rel="nofollow noreferrer">Google tutorial</a></p>
  
  <p>and </p>
  
  <p><a href="https://stackoverflow.com/questions/23736137/onconnectionfailed-geving-sign-in-required">Stackoverflow</a></p>
  
  <p>But the problem is leaderboard is getting displayed only for testers and not for other users.</p>
