iPod Mini Shuffle no longer syncs to iMusic
So I have a waterproof iPod Mini shuffle that I use while swimming. Recently I tried to sync it to iTunes but iTunes no longer exists and it's now iMusic. For some reason, iMusic doesn't recognize my device. I would love to add/edit my swim list. Can anyone shed any light on how to resolve my problem. My Mac laptop is OS Catalina 10.15.7 Not sure what my shuffle is because I can't connect it, LOL.
