iTunes / iPhone sync issue
I have a strange issue where albums unchecked from iTunes > device music list and then synced remaining on iPhone. I tried deleting the two albums manually from my iPhone, then re-syncing. They are put back on! :-/ I then tried unchecking all checked albums and syncing again. Everything is removed, but the two albums I'm having the issue with. Anyone else seen this or have any idea how to fix? Don't think I've had this issue before.
iPhone 11 & iTunes are up to date. I'm on a Windows 10 PC.
