I’m pretty sure this issue started before 4.0 was released
And I think it started with the last tvOS update
When you’re at the home screen and have the Channels app highlighted the recent DVR recordings icons are not updating.
In my screenshot you can see American dad is listed as an icon
But when I go to my DVR listings it’s been deleted for a day already.
It seems like the only time it refreshes now is after I fully reboot the Apple TV and re-launch the Channels app but then it’s just a one time refresh and the icons hold and never refresh again.
