Playing an episode from the Up Next doesn't open the app for the service
When playing an episode of a show from Up Next it will sometimes prompt to subscribe to the channel for the show. But I'm already subscribed, and already have the associated app installed. This happens consistently with Paramount+, Showtime, and Starz, and occasionally with Disney+ and Max. Hulu (and AppleTV+ obviously) appears to be the only non-Apple service that always opens properly.
I've tried everything short of a factory reset. Force quitting everything, including the TV app itself, rebooting, checking for updates. Even opening the show page and selecting the app to use. That does then play the show but it goes back to not working after.
