I updated my spotify app on my iPhone 6 last week. However, nothing has been the same since. I can open up Spotify and see all of my playlists. I can click on one, and a song will play. One song will play and nothing more. I have tried using it in different areas to see if it was my personal wifi connection that was the problem, but this is not the case. I have also deleted and adding the app back, but I still encounter the same issue. I don't know if this is worth noting, but my Mac desktop plays music with no problem. It is just my app. My phone has never had an issue with any other app.
