Did something change in the apple TV app? I can no longer find old recordings. The recordings menu takes me to the list of “recent” recordings, showing me several of the most recently recorded shows. But I can’t find the other view that lets you select a particular show and see all of that shows recordings.
Either they fixed the problem or it is limited to few. My Apple TV this morning shows all of my past/present recordings. Have you tried uninstalling/reinstalling the Tablo app? Hope this problem gets resolved for you.
