I recently deleted my music library files during an over-zealous MacBook clear out. Now I can't sync my music library at all!
When opening Apple Music I have nothing in may library (although I have lots of songs saved etc on my iPhone) -
I get an error message: "The music library file cannot not be saved. The required file cannot be found."
I think it is because I deleted it but how to I re-build a library file to match my account and sync as per my iPhone etc??
