Updated this am. Was the version number in the message. Still had continue gem error. Now open game and get box to force update. Go to App Store and no update available. Just button to open game. Should I delete and reinstall? (I am signed in with Game Center)
Try this first: in the App Store or Game play, swipe down (pull down on the screen) with your finger to refresh the apps…it should show you new app updates ready for install.
