The subject says it all. Recently updated phone to iOS 8.1, noticed this problem today. Spotify will stop playing the track as soon as I leave the app (regardless of how I leave it), and refuses to play unless I'm in the application.
Looked through the forums... seems like some people had this problem a while ago, but nothing super recent. Thoughts beyond uninstalling/reinstalling? Really don't want to have to wait for all of my music to redownload to be stored locally if possible.
Thanks in advance for any assistance!
