Cant restore my purchases and glitches

It says that its going to restore my purchases but it glitches ... This only happened after the update for the iOS 8 ... Idk if its the iOS 8 update or if its the app but I think weemee needs to have and update for the app... Anyways its a really fun game its just that one problem
