Shared playlist is empty
I created music in Garageband, exported as mp3 files, and imported into Apple Music. I've created a playlist for them, which I can see and play on all my devices, but when I try to share the playlist with others, it is empty. They can see the shell, but no songs are there. Please help! (Note: this question has been asked so many times, I really hope that by this time you can do better than "contact apple support").
