UPDATE - it works and here is how (saw this answer buried in between all of us being upset
hold the button on the top right of your apple remote. You will see a menu pop up and at the bottom is where you can select what device you want to send audio to over airplay. Feel relief that it works. Still to upset at the disregard for all the collateral damage caused to me and everyone else that could have been so easily solved with any number of communication methods. Maybe a pop up on the Apple TV. Or maybe an email communication, since we know apple isn't shy about those. Really bad customer experience guys. You k is what that is right? Customer experience, not a bunch of zombies no matter what you might chuckle about. Poor form if it were done by some new app on the App Store. Incredibly arrogant when done by one of the most profitable companies in the world that still cares most about locking people into them.

$6,000 Hegel receiver airplay certified no longer shows up in Apple TV. iPhone sees it fine. Happened to upgrade WiFi router around the same time as update. 2 routers, 8 - 12 hours, and a fight with my wife later, and you have got to be kidding me. The audacity. The reason I always hated apple, the company that tells everyone else to think different. Try looking in the mirror. Bill gates could be behind COVID and I'd still like you less.
