This happened to me a couple of months ago and is happening again. I connect to the wifi network at work. "Offline" is not on. I can't access anything except whatever I was last playing. I can access the the list of musicians I follow but can't click through to their pages. I tried restarting Spotify. I tried restarting my phone. I tried reinstalling Spotify. Nothing works. The app won't even work on LTE. The app is completely unusuable now.
