tvOS 13 is not finding HomeKit running on iOS 12
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
