The game is Wild Racing 9 (the made-for-china version of Asphalt 9) and when you launch it, it tries to download an appgallery ad, but since I'm quite far from the chinese servers (I'm from Costa Rica) it mostly times out.
And no the "Don't show again" option does not get rid of all ads. It just does not show that specific ad in general.
Thats like complaining you got food poisoning from gas station sushi.
Still making it look like you can get rid of the ads but it doesn't do that is assholedesign anyways, because they make it a don't show again button, but they don't say it only applies to that specific ad. Meaning they can push different ads to you
