Sends you to the App Store mid game. – Live Chess Review

I play chess on this app every day. I like it a lot, but for some reason recently in the last month or so, all the sudden it sends you to the App Store. Once I lost the game data over it when I tried to get out and go back to the game. This actually just barely happened which is why I'm writing this review. Please fix it.
