YouTube flat-out does not work in desktop mode anymore. A couple of other side are also have gotten their desktop mode broken.
why wouldn’t you try to replace m with www on the URL bar?
Doesn’t work, it forcefully opens the m.youtube site if I type that URL in ,the site is not the actual mobile YouTube site, it’s can’t play video. It needs an external player.
Deleted site settings for all YouTube related stuff and it works now.
