I used the Advance Filter to save a smart playlist (very cool addition) and I can get it to show up on my TV library’s Recommended page, but I can’t get it to show up on my friend’s TV Recommended page. I did an identical one for Movies and they can see that one just fine.
I thought maybe my TV library was corrupt but I tried a test TV library and I am getting the same result.
After some more testing it looks like if you add a custom playlist to a user’s Home or Recommended views (via the “Visible on…” menu), it completely removes any TV recommended listings.
