Okay, I'm back… and confused again.
I'm digging a little deeper into trying to use the Music app on my computer to create and manage new playlists on my iPhone, but weirdly, all I see within the Music app is a long list of old playlists that have not been on my phone in years. To be clear, this is under the heading on the left that says Playlists. None of the (very few) current playlists actually ON my phone are amongst those listed.
When I click on my phone's name under Devices, just above Playlists on the left… then I am able to see all the individual song files that are in fact on my phone right now. And I am able to view them by Title, Artist, Album, etc… But I am NOT able to see any of my actual playlists when in this Device/phone access space...
Do I have to manually delete all the old and now meaningless playlist in the left column to get rid of them? And then, perhaps recreate new playlists there? (I've not tried that yet, but I'm guessing this may be the only place to do so)...
I seem to be being encouraged to use Autofill? I still see no naturally intuitive place to continue to create and maintain my playlists manually...
Help?
