Montana sundown

I like this game a lot but lately it doesn’t give me my rewards. For instance the x2 800coins or evening getting to the next board. It gets done with the ad but then the screen goes black...except for the ad at the top of the screen sometimes. More often than not I’m having to get out of the game completely and get back in......it’s very frustrating to do that and get the same issue again...kinda makes me want to not bother. Ads are one thing but you should get the gameplay once they’re done. Please see to this issue . I thought it was a specific ad but that’s not the case.
