Apple TV not showing Playlist Thumbnails (Catalina)
After installing Catalina, I created thumbnails for 25 Smart Playlists in the new TV app for my Home Videos. When viewing via Apple TV on my television, a Playlist thumbnail only shows up after I select the Playlist, defeating the purpose of having thumbnails to help me identify which Playlist to choose (I have trouble reading the Playlist names in the small print on the TV).
There is nothing but cogwheels in the list of Playlists of my Home Videos (first photo of my TV's screen below) although the thumbnail for each Playlist is clearly accessible to Apple TV (for example, see second image below, which is the TV screen after selecting the first Playlist from the list of Playlists). Seems like this should be an easy fix. I remember the days when I loved to show Apple TV off to my friends, but a screen full of empty cogwheels is not what I expect from Apple and, quite frankly, doesn't help its own reputation with my Windows-using friends.
(BTW, the thumbnail of the Playlist in the 2nd image below is a jpeg screenshot of a video, not a video file itself.)
Restarting Apple TV and the TV app was no help (again, it is not an issue of Apple TV not accessing the thumbnail, as evidenced by the 2nd photo below).
Any thoughts how to get thumbnails to show on the Playlist screen on Apple TV? Thanks.
