Is YouTube fucked up just for me or others too?

Navigating to a video does not work, it changes the title and acts like it has navigated to the new video but shows the old one.

Happens sometimes for me. That usually happens when the new video ist rated r18. The confirmation doesn't show and therefore it plays the last one. Sometimes it will just stay black though.

Refreshing the page always helped in that case.

Well, the mobile app definetly is.

My windows machin can no longer play yt vids. Don't know why, every once in a while some random video can play. I get lots of CORS warnings in the console and sometimes the preview pictures don't show up... I'm watching youtube videos on my tablet only for a few weeks because of that. Oh, and it's no browser issue. All other browsers are the same (vlc doesn't work, too). I also checked my hosts file and flushed the dns cache... Didn't work
