Hi everyone please please help me solve this situation since I really rely on spotify for music.

So my spotify won't play on my iphone 6 at all.  When I go to browse and click "shuffle", usually there would be a box pop up underneath that says the song title and if it's playing or paused.  However, mine is just a greyed out box or sometime it just doesn't responde at all.  It will play on my computer but just not my iphone.  I've removed and reinstalled multiple times and restarted my phone and it is still not fixed.  My spotify is thd most updated version too, so I really don't know what's wrong with it.

Thank you!
