I followed this tutorial for integrating Google Play Game Services (GPGS) into my game: http://coronalabs.com/blog/2013/06/25/tutorial-introducing-google-play-game-services/
Everything seems to be working correctly, except no scores are being posted to the leaderboard. Players are able to login and view leaderboards, but they are empty. The leaderboard says “There are no public high scores for this game.”
The app is published and so is the ‘game services’ that is linked to it.
Any help would be greatly appreciated, thank you!

submitScoreListener is called later in main by pressing a “Leaderboard button” in the game
[lua]globalHighBtn = display.newImage(‘global_hs.png’, -1, display.contentHeight)
transition.to(globalHighBtn, {time = 0, delay=2000, x=320, y = 1170, onComplete = function() globalHighBtn:addEventListener(‘tap’, submitScoreListener) end})[/lua]
There are three leaderboards (easy, normal, hard)
‘difficulty’ is a variable that says if game is in easy, normal, or hard mode (1,2,or 3) - this is working correctly when submitScoreListener is called
highScore1, highScore2, and highScore3 all working correctly when submitScoreListener is called
adb logcat in command prompt (when submitScoreListener() is called):
