I've seen similar posts here after doing a search, but have found no solution.  

I have my spotify connected to my facebook (but have disconnected and reconnected it while attempting to triage this).  My girlfriend does not have a facebook account and only has a spotify account.  I'm following her and she's following me.  On the desktop client, I'm able to send her songs.  

On the iOS app (both iPhone and iPad), when I go to share and type in her account name, she does not come up.  If I do a search for spotify:user:heraccount, it shows me her account name and pictureless icon but nothing else as to whether or not we're following one another or allowing me to share anything with her.  

I've tried everything to get this to work and have googled extensively for any solutions and have found none.  I've been a spotify user for quite some time (and I'm a premium user, for that matter) and I remember being able to share with people who weren't on facebook.  I know some changes have gone underway, has this affected sharing?  Even if I was sharing with a friend who has a facebook, I wouldn't want the song going to their facebook account or for what they send me to go to mine.  I want to work exclusively through spotify and the only reason I even connected to facebook was so I wouldn't be a pictureless picture.

Is there no solution to sharing on the iOS devices?
