Flip a coin and that's how it seems the game developers decide if the app will work properly or not. Oh hey, play some ads for extra credits... Oh wait, we don't feel like playing ads today... Yep, that pretty much sums it up. Done with this game, will try another more reliable one. If the game developers want more info, they need to play their own product and I have zero doubt they'll see the issue within a day or two. Asking players to send screenshots of what are clearly known issues is lazy.
