Home Sharing - "No Libraries Available"
"No libraries available", AppleTV not finding libraries since most recent MacOS and AppleTV updates.
All devices are running current software. I have made sure that the MacOS is authorized for AppleID. TV app on iMac is up-to-date and authorized. Media sharing / Home Sharing is turned on via system preferences. I have signed out and back in home sharing on iMac and AppleTV. I have de- and re-authrorized TV app on iMac. All devices are on the same network. All AppleTVs where able to see libraries and play music/video prior to newest updates.
Apple TV 4K, tvOS 14
