Hi, I'm having a problem with a crash out of game and would like to know if it's just my iPhone 7plus or not. I will start the ads for the free gold, cash and race skips and the game crashes after about 5-6 videos played back to back. What's wiered is that I see the cash or gold count go up, then after the crash it drops back down. It's watching ads and getting nothing for free as it states.
