Same here. I set my ads to medium. After I click 2 ads on mobile, it automatically plays but when I try to tap on fullscreen, it always pops an ads. I tried to tap fullscreen 20 times but no luck, only ads popups.I checked without incognito mode, using Firefox. The result is the same. I get 2 ads from clicking the play button and then I get one ad on every first or second click on the player. And I have set the earning mode to ZERO
