Non-apple music purchased music disappeared from iphone
I have a fairly large collection of non-apple music mp3 collected from various sources (bandcamp downloads, cd rips, old hard drives) that I had on my iPhone 11. I recently updated my iphone and cannot see these mp3s in apple music. When I plug my IPhone into my laptop it lists all these mp3s as still being on the device. I tried to manually put the songs back on the IPhone but was only partially successful, a fair amount of them wouldn't take no matter how many times I tried. WTF?
