Looks like Channels updated itself.... got the "Setting up" screen as I fired it up on my Apple TV 4K this evening.... I have my settings set to open the Library, showing the "Up Next" level, with other stuff below. Anyway, today's recordings aren't showing up in the "Up Next" like they usually do... so I think they didn't record, but no, they're there, but down in the "TV Shows" section. One single recording for each TV series... so why aren't they in the "Up Next" category? It's many more clicks to get to the newest 1-show recordings... what changed? Any way I can change it back?
Are you using the TestFlight beta?
I don't believe so...? I have 2022.04.28.1311 - I have installed betas before, but don't know if they auto-install when a new beta comes out, or if they're manual-install only.
What version is shown on your Apple TV in Settings > About
Apple TV version is 15.5.1
Channels version (in About Channels) is 5.4.1
