That really isn’t helpful. I have updated the game. Version 1.173.1.1 Not familiar with how to clear the cache on an iPhone. At this stage, as far as I can see, the bug still exists - despite what the professionals have done.
Just force closed and restarted again. Twice. No change. Lost two lives. The bug has not been fixed for my iPhone. Frustrating. It’s not even a hard level!
