My album artwork won't sync to my devices and they frequently delete my synced music after transferring my iTunes library to Apple Music
I don't use any subscription service. My Mac with iTunes got obsoleted and I had to move my iTunes library to a newer Mac with Apple Music on it. Ever since then I have had these issues with syncing my music to my devices. The album artwork does not transfer over to my devices, and seemingly at random, music that I've synced that I was listening to just fine a few weeks ago will just disappear when I attempt to play it. I have to delete all my music from my phone and resync it all to get it back.
I'm using Apple Music 1.2.5.7 on OS X Monterey 12.6.2, syncing to an iPhone 13 with the latest iOS 16.2 and iPad with iPadOS 16.2.
I have a growing impression that Apple just doesn't consider my use case important anymore, they'd rather only support subscribers who stream Apple's music. So, alternatively, is Apple Music still the only way to get my own music files onto my phone? I'd like to migrate to an app that seems more focused on my use case and my needs.
