I play on an iPad. I completed level 665 and made the in-app purchase for the next episode like I've done 664 times before but it locks up. If I close the window and try again I get a message that says the purchase has already been made and will be restored for free. The circle just keeps spinning and the X is grayed out so I can't close the window. I was going to re-install Candy Crush but I don't want to risk losing my progress.
