Game hangs often – Christmas Sweeper 3 Review

I have been having problems both on iPad and iPhone with this app. At least once per day it hangs - will not let me make any moves. Also, multiple times a day the app exits - either right before or right after the ads. My other peeve is that you do not get any stars when you play one of the challenges - like rudolf, bubbles, etc. I like to play them because I can go on to the more challenging levels. I didn’t realize until recently that there were no added stars.
