Apple TV does not show up anymore in Apple configurator when its running tvOS 27.2. I tried multiple solutions, including a solution that did the trick for older OSes (26.4), but does not work on the latest OS, see https://discussions.apple.com/thread/256274272?sortBy=ran
Somebody there already mentioned this as a comment with a lot of upvotes as multiple people (including me) are experiencing the issue, and would like to get this resolved. As its currently not possible to onboard any apple TV with the latest OS, which is really annoying for businesses like ourselves.
Furthermore this seems to be a longstanding issue, which people only got to work with a workaround. I would be nice if the actual issue can get fixed instead of us having to find loopholes to make it work:)
