Bought a preowned TV 4K. It was finding my HomeKit running on iPhone 6, iOS 12 (latest). To get rid of prior owner's config did a reset/update. Now on tvOS 13 but it no longer lists my HomeKit. Am guessing prior version was tvOS 12. Is there a compatibility issue? I've done a ton of resets and restarts and also rebuilt my Home app all with no luck. Also, I see there is no way to downgrade from 13 to 12.
Apple TV 4K, tvOS 13
Called Apple Support. The problem was that the AirPlay 2 support was not activated. To get that activated, had to navigate to AirPlay and HomeKit then click on Room. That brought up a screen on tvOS prompting to activate BlueTooth on my iPhone. It took some work [1] to get that screen to go away, i.e. for the iOS to tvOS BT connection to occur but eventually the BT prompt screen did go away and then my HomeKit hub was shown on the AirPlay and HomeKit screen. It took another half hour or so for the iOS HomeKit app to connect, i.e. for HOME HUBS to appear on the Home app's screen which appears when you tap the house icon and for something other than a help screen to show up when pressing the Automation button.
[1] I don't remember exactly what magic finally worked. I think it was closing out and restarting the Settings and Home apps.

Yep, Noticed that. I might (hopefully) be wrong but I have a suspicion tvOS 13.x can't find HomeKits that are set up on iOS 12.x (iPhone 6), but Apple is still supporting that phone; I got an iOS update just a few days ago.
Hello,
I am sorry, you cannot revert to a previous version of Apple TV’s system software.
tvOS 13 is not finding HomeKit running on iOS 12
