Why does my iphone repeatedly remove all music that I added via my mac, leaving me with only those songs purchased from itunes?
At least 5 times now I have spent an hour transferring playlists and songs from my mac to my iphone using a lightning cable. The music is properly transferred and works fine. Within a day or two I will find that all music and playlists I added have been removed from my iphone and all that remains are songs that have been purchased previously. How can I prevent this from continuing to happen?
Mac mini, macOS 13.5
