I can now connect to my various Apple TVs and Home Pods with the second beta of 11.3 (I couldn't even connect before) but I am unable to play Music to these various speakers. I've removed all Norton and Symatec files (I think) as that seemed to cause a lot of problems for folks. Does anyone else have this issue? I've done quite a bit of research and I can't find anything. I'm using a late edition MBP from 2016 and everything worked like a top until I installed Big Sur. Thank you in advance!
