Game freezes after one game – Gutterball: Golden Pin Bowling HD Free Review

I actually enjoy this, but there is one problem. After finishing a game, the game freezes on a loading screen. Even after waiting a long time doesn't work, but it might be my old iPad. Only solution is to restart the app. If you could fix this, I would appreciate it.
