Unstoppable PopUps on mobile? [View all]

Hi,

About 50% of the time I log in on my phone lately I’m getting pop ups that I can’t close (ostensibly for Spectrum, but I haven’t tapped them.) And then there’s about a 50% chance of them appearing any time I open a new thread to read.

Is this a me problem, or a DU problem? I don’t get them at any other sites, and it’s making DU almost unreadable!

Help!
