I can't download songs,even though the download using cellular is on.When i download songs or play list it says go to setting to download using cellular.
Hope you are okay, sorry to hear you are having issues with your Spotify.
Please could you try a re-install of the application, I will attach a guide to make sure it is completly removed from the device before installing again :)
Let me know how it goes :)
If you un-install Spotify, all downloaded songs will be removed unfortunately.
