Latest TestFlight version installed on tvOS 18. I've incorporated a handul of STRM files into my Channels library and they play nicely, for the most part. When playing these streams, the timeline doesn't update to reflect the current watch state. And I can't scrub through the timeline to jump halfway through, either. I have to skip ahead 30 seconds very many times, or hold down the fast-forward button for a very long time. But even still, the timeline marker display doesn't update.
Is this just how STRM files are expected to operate in Channels, or is this a bug?
