Don't have experience with Apple products, but have had zero problems with ads or pop-ups for quite a long time on my laptop and android tablet or phone. On the Windows laptop, I use Chrome with 2 extensions, uBlock Origin and Disconnect. On the phone and tablet, I use the newest browser from Cheetah Mobile, Armorfly. Previously used CM browser, but like Armorfly better and also use the CM Security.

Today I had a breakthrough, it eventually stops if you keep reloading the page and I noticed it almost exclusively happens with one particular banner ad: "Download the free Twitter app". If you keep reloading the search page, you'll eventually get served up a different banner ad than the "twitter app" one. It you get the "download the free twitter app" banner ad, it is almost instantaneously triggers the "Open this page in "App Store"?"
