I deleted the app to try to stop it from booting me out of the game when I get to where the levels window is, I touch the level to play and get booted off. Deleted it then downloaded the updated version thinking that would stop the glitch, it restored to my current level but not my boosters!!! Fix this bug or I am gone! My cheap android phone plays it with no problem why can't I play on my mini iPad without problems. My OS on my mini is up to date so it should not be a problem.
