Whenever a new release of Roomie comes out, I make sure to update my phone and all 3 iPads we use in the various rooms, so they all work consistently. I am also using a 2022 AppleTV 4K as my primary. I have not updated it since I installed it a year ago. At what point do I need to update it in order to keep it compatible with the Roomie releases for my iOS and iPadOS devices?
Always update tvOS or iOS to minor releases ASAP. Always update Roomie with same logic. It would be reasonable to pause and check here before major releases.
