I have been having problems with the (star) rating for my songs aren't syncing between my iMac and my iPhone & iPad. Usually if i add the a rating to my iPhone or iPad it syncs to my iMac. However, when i add a rating (ex. 4 stars) on my iPhone, it doesn't sync to my iMac. Does anyone else have this problem? I don't sync my music via USB. I also use the iCloud Music Library and iTunes match (i also pay for Apple Music, but i mostly use my own purchased music that i had before i started using Apple Music.
