As far as I know since December 8th spotify mobile users are supposed to be able to change their playlists cover photo and add descriptions by going to the three dots and then selecting the "edit" option. But the edit option doesn't appear on my account, I've tried signing out and back in as well as deleting and reinstalling the app, but nothing's worked.

I'm on IOS, I haven't asked anyone I know with IOS devices if they've been having them same problem yet, but I know that the people I know who use Androids have the option to change their cover photos. 
So is this just not out yet on IOS? Or is there a way to fix this?
