Hi there. I am have just updated my Big Sur beta to the latest version. Since updating; I have been experiencing major issues on Safari with some of my streaming services; mainly Netflix, Youtube, HBO Max and Prime Video. I researched a bit and found fixes by switching the VP9 Decoder setting off. This fix has helped only for YouTube but I still experience streaming issues with the other services. Does anyone know of any other fix I can use to solve this issue? I would sincerely appreciate the assistance!
