That's strange, I run safari on mac and it has worked fine for the last couple of years for me? Is it coming up with any errors or just not blocking ads?
I'm guessing its trying to get people to download the new not606 app which appears to have just been released yesterday? I'll check it out
It was the download link that "failed to load". I have downloaded from the App Store now and it seems to have worked and be working.
The search not appearing could well just be my phone - trying to use an android app on a non-android phone.
