I've had the 4th gen Apple TV since last October and am experiencing a very annoying issue with TV channel apps. First, I authorize the apps on my computer and successfully sign in on the ATV. Then I can watch without problems for a few days to a week later. After that period I get an error message "no authz" when trying to watch programming. This happens for every single TV app and it's annoying when you have 10+ apps doing the same thing. It got to the point where I stopped using the ATV4 and I'm even considering selling it just because it's sitting here collecting dust. Has anyone experienced this issue and if so, do you have a solution for it? I called Apple support and they said there's nothing I can do but restore it and reinstall the apps. I've tried that numerous times..
