We are not talking about the radio function (or at least I'm not). We are talking EVERYTHING! Search for a band and click on their name and it will not load a list of songs or anything!
HOWEVER, I found (on mine at least) that playlists still work!!! (as in previously created user playlists - created by me)
Suddenly its fixed, it just came back to normal without any action by me, guess the Spotify staff has taken care of it.
