Personal music transferred from old phone to new phone does not appear in Music app when new phone connected to laptop
I recently upgraded from an iPhone XS to an iPhone 14 Pro. I have music downloaded from many different sources on my laptop which were also on my phone. I transferred all my data from the old phone to the new phone and it all appears to be there. I can listen to all the music on my new phone. The problem is when I plug the new phone in to manage the music on it, it appears as though there is no music on the new phone in the Music app.
I would like to be able to see the music on my phone and delete things and add things but currently, it just looks there is no music there.
Does anyone have any ideas?
iPhone 14 Pro, iOS 16
