What you can do is go to the Google Play Store >> My apps tab and see if there are any updates available manually. You can also do so by typing in the specific app and seeing if there's an Update option along side Uninstall. As I see, the last update was made on June 11, 2015, which was yesterday, if you're in New York like me.  You should try updating again if you didn't since June 11. 

If you check and you are updated, you probably have to update Google Play Services here, which was updated on the 4th of June, 2015. 

If neither of these methods work, it means Google needs to release another fixed update.
