I love this addictive game, but during the past 3-4 days, when I click on, "Watch Ad," the game closes. I've sent your Developers an email regarding this problem where I asked whether there was anything I can do on my end to prevent this annoying issue from happening or whether this issue is on your end? I cleared the cache which seemed to help, but 2 ads later, it occurred again. Should I try clearing data as well as the cache? Any guidance would be very much appreciated.
