Difficulties with playing YouTube videos in Big Sur beta in Safari I was trying to play YouTube videos in Safari v14.0 (16610.1.23.1.3) in Big Sur beta, but it doesn't work, playing window is black and after click into it I get a message that an error occured. Does someone has solution for this one?
Okay guys, I solve the problem. It was causing AdBlock extension for Safari, I uninstalled it and installed AdGuard and now it works like a charm.
