Freezing and crashing

I love this app but recently it keeps freezing in the middle of the game. It happened 3 times in a row :( Ive been playing for a few years on and off and it never has done this. Maybe its the update, but it needs to be fixed! It doesnt save my success and I had to replay the party game again for 1,000 coins just because it froze :(
