I do not know if this is specific to iOS 15 or not, but I have found since the update, that ad blockers which previously worked well, are now letting ads through, willynilly.
So, I’m seeking recommendations. What I have used so far: Adguard, Adgard Pro, Ghostery (the extension not the browser) and Block Bear (which seems like the simplest and which until recently was working really well. No, havent been using them at the same time.
Anyone?
