"Try Now" Pop-Ups

Does anyone know how to make these pop-ups go away? I have a one-year subscription to Acrobat Pro DC, and I'm kicking myself daily for not just buying the desktop version. I can't do any work with the incessant interruptions. It is notable that none of them have been related to what I was trying to do at the time.
First-line chat support has no idea how to solve the problem. I've been told I'm running the wrong software. (I'm not.) I've been told to update. (No updates available.) I've been told to do things that have nothing to do with the problem. (Support backed down on that.) I've been asked to share my screen for something that should just be a simple setting. (No screensharing with the clueless.)
I'm awaiting a call back, but I'm quickly losing faith. The behavior is clearly intended, and I think Adobe wants to make it hard to turn off.
