iTunes Match not syncing custom lyrics and comments correctly
I use a MBP and an iMac both with the latest software, macOS Monterey 12.4 and also an iPhone (iOS 15.5)
I have an active iTunes Match and Apple Music subscription, all devices are supposed to sync (enabled) but
when I change song info like comments and lyrics on 1 Mac,
- they are correctly synced to iPhone
- comments are correctly synced between MBP and iMac but REVERT when I play the song
- custom lyrics are NOT synced at all, not even after a 'forced' sync by modifying other info, like comments
any suggestions?
