Since at least iOS 9 (I think), I have been using Purify, which has been a wonderful ad blocker. With the upgrade to iOS, Purify doesn't seem to be as effective at blocking ads, especially some of the more dynamic ones. This is a problem I'm also seeing on my Mac with Safari 12. This seems very unlike Apple--to make content blockers less effective, but that seems to be the result (perhaps inadvertent) of upgrading to iOS 12. Anyone else experiencing similar issues?
