The ads that seem to not award boosters and just end your game are the ones that don’t have countdown times for the reward. When you hit the X on ad your done, usually bumped out of the game. It doesn’t matter how long you wait before hitting the X and the ad will not exit on its own. If it is a multi step reward like 4, 1, spaceship. You might earn the 4 moves before you hit one of those ads, but that is all you get, it takes you back to the game immediately. These ads also cause you to not earn anything in other scenarios, and bump you out of the thing you were doing like Sweet Cinema. Some example of the troublesome ads are Suduko, Jigsaw Puzzels, Color by Number, and Match 3 ads. I know you are working on this, but thought these details might help pinpoint the problem. Thanks!
