It seems I'm running an ad blocker and Youtube doesn't like it. Next time, they're going to lock me out. I have no idea what it is, how it got there or how I find it. Any pointers please?
It will be a plugin running in your browser. Top right in Chrome. I just use Edge for youtube now and Chrome for everything else, not removing the adblocker for one site.
Although it seems inconsistent, it's only one browser on one computer that is impacted.
