In any Google play game I cannot view the achievements any more, the window flashes open then closed. In the Google play app it will show the amount, ie 2/14, but clicking on 'my achievements' shows a blank page. Leaderboards work though!
Ive removed my account from my Nexus 7 and added a different one, the achievements will show, but as its a new account it shows 0/10 for the games and clicking on them shows the achievements and the pictures. Removing this and adding my old one goes back to the same error, under each game it will say how many i have, 4/10, but will not open to view the individual achievements and they will not unlock in game.

Only suggestion I have left is a factory wipe, if you cannot test on another device.
