I'm pretty much convinced that the "X" in the upper right corner of the ads that show up at the bottom of the screen when on mobile (not app, just mobile internet browser) doesn't actually work to remove the ads, they're just there to rack up clicks on the ads. Every time I try to click that X it opens up the ad in a new tab - and I *know* I'm clicking on the X and not fat-fingering it. Haven't been able to get those ads to go away with the X...ever...so I'm stuck with them.
