I am currently in the "Playlists" tab in My Music and I can't see any option to sort playlists alphabetically? I just have edit in the top right hand corner which brings up the option to delete playlists I have created
Oobermann: Dry dragging the screen down a bit and a filterbox should be visible. To the right of this is a button that lets you choose sorting method. If you don't see the filterbox try to force quit the app and restart. I had to do this.
