Brief description of the issue:

Spotify iOS app crashes after 30 seconds of being open/playing a song.
App only crashes when using Wi-fi. App does not crash on cellular or on offline mode.

When the app crashes, it closes and shows the home screen but if you double-tap the home button on the iphone it shows that spotify is still open in the background.

If i open spotify up again it loads as if it was closed the whole time.

Steps to reproduce the issue:

1. open spotify app
2. play any song/album
3. app stops playing music and closes
