I've seen a number of references to this feature, such as:
Even Spotify support told me via email this was true, only last week !!!
So what's happening????
I have (when it works, which is rare) about 2500 tunes in a number of playlists. But when I go to Songs (All Songs) I have about 30 tracks.
So I still need to go to every single playlist one at a time and select download to get working offline.
Maybe this is linked to my other problem:
Samsung Galaxy S4 Mini
Spotify = 188.8.131.528
Android = 4.4.2
