My concern is discussed in this recent topic and seems to be central to this topic from 2017.
From what I understand, we are not able to create metadata for our own media as a “TV Show”. Custom movies are relatively easy, of course.
So far, I haven’t gotten the trick working that @james described in the 2017 thread but it’s not a good solution.
I know there are complications that aren’t obvious to users but I think Firecore needs to consider allowing a method for us to define our own media as “TV Shows”.
