Apple TV "Unable to browser folder"

I recently signed up for Apple TV and logged in through PlayOn, and I was able to record 4 seasons of a TV show except for the last episode, and now no matter I do I am not able to record the failed episode or view anything in the Apple TV+ channel. I get an error message "Unable to browse folder" and "This folder contains no content". I have tried restarting the media server and PlayOn in general. I have logged out and back in to Apple TV, I have tried on two computers. I am able to log in through the PlayOn pop up window and view videos on Apple TV inside that window. But no luck with anything else. Has Apple just changed something and PlayOn needs to be updated?
