I'm quoting myself because what I originally said is no longer true. This morning, the pop ups are back for me on my Macbook. I am able to use my old PC without pop ups (so far).
It's still happening to me also. On my laptop right now and had to close my browser several times and go back on the Dis just to check things and try to type a quick post. I haven't checked my other devices yet this morning.
I changed my vote from "No" (because I usually don't use my smartphone to disboards), to "Yes, but just on this site and on any device", because I get it on my phone and on my laptop. Laptop just started last week.
