Spotify keeps not working whenever I am not using wi fi. Initially, it would not play any music when I was not on wi fi, even though the music was already downloaded. I also do have data if it had been needed. I then deleted the cache, reinstalled and restarted the phone - since then I can’t now log into Spotify as it just says I am offline. The username and password are correct as I can use them to log in on the Spotify website. Have tried reinstalling and restarting again, no luck. Any ideas what I can do to get it working normally again?
