I have created playlists & YES I've chosen to publish them. When my sister looks at my account she can't see any of my playlists, but she can see my boyfriend's playlists, and he's done the exact same thing as me. When she looks at my account she can only "send me one of her favorite tracks" and no matter where she clicks she can't seem to get past that.
I've seen that people with similar problems have 2 accounts which are not linked, but I have connected my facebook account with my spotify account already. I have premium and everything looks just fine when I check the preferences.
