Why can't I download a 'home video' from my iTunes library onto my iPhone (apple tv app)?
I have a home-recorded video in my iTunes Library (Mac Mini). I can connect my iPad and copy ("sync") selected videos from the library onto the iPad, when the iPad mounts as a 'device' in iTunes.
However, when I do a similar thing with my iPhone (a new iPhone 12), it does mount as a device in iTunes and I see it in iTunes (left sidebar). But when I check any of its sub-areas (Movies, TV Shows) they are empty, except for Music (which has a couple of audiobooks) -- and the video categories remain empty even after I do a 'sync'.
On the iPad, I can select videos (when set on the Library/Home Videos left-sidebar) and 'drag' the videos onto the iPad icon in the left sidebar. That works nicely. When I try the same thing when the iPhone is connected, nothing happens. Alternatively, I can select the iPhone icon in the left sidebar and (right-click) select Sync. iTunes shows that it's going through 4 steps but nothing ends up on the iPhone (in its Apple TV app).
What can I try next?
iPhone 12 Pro Max, iOS 14
