Obtrusive ads

Every time I finish a level, I get a pop-up ad telling me I can "improve my aim" by watching a video. I dont want to improve my aim, so I click the "x" box. Then the same ad pops up after the next round, and the round after that, and never goes away until I waste my time watching the stupid video.
