Zoo Puzzles for kids 2-5

I purchased the full version of the game. The graphics are beautiful, and so are the colors and the art style but the game has a glitch. When you finish one puzzle and you go to choose the next it freezes. Every single time. Without fail. I bought this for my two year old nephew and he loves the game but it’s disappointing when I have to continuously close the game and reopen it just to get it to work for one more puzzle. If you could issue a patch to fix it that would be great. I’d hate to uninstall it and basically just waste my money.
