Unable to start Home Sharing between Mac running Big Sur and new Apple TV

Hello:

I'm unble to start Home Sharing between my Mac running Big Sur and my new Apple TV. I have both devices on the same Wifi network. I even tried Blue Tooth and that didn't work. I have enabled media sharing and Home Sharing in my System Preferences. However, the Apple TV still can't find the TV app library on my Mac. Can someone please point me in the right direction? I've reda the previous guides on this site and they don't seem to help.

I appreciate everyone's help on this. :-)
