Playlists no longer available offline after updating iPad app

[supportmusic]

Hi,

I am a Premium user who just updated the Spotify iPad app this evening. After I did so, I noticed that all of the playlists I previously had available for offline listening are no longer able to be listened to offline. I was able to re-download a few for offline listening, but I had hundreds available for offline listening before, so that's not a feasible solution. 

Thanks in advance for your help!
