Crashes way too much, cannot claim rewards

I enjoy playing, when I can. This app crashes repeatedly, Im not allowed to access my rewards, I cannot watch the videos to earn gems. Ive deleted and re-downloaded the app but it continues to crash. There are no options to switch between missions. Please fix these problems and I will enjoy this app much more and change my review.
