For most of these users, force closing the game and resetting the iPhone/iPad fixes the problem. Follow the instructions below to 1) force close the game and 2) reset your iPhone/iPad.
If the problem continues, try uninstalling the game and reinstalling it again.
And if that doesn't work, please contact us and we will be glad to help.
