Continually kicked out of Spotify on iPad2

[bigekram]

For months now, I keep getting kicked out of Spotify on my iPad2 after a period of time (sometimes 15-20 minutes, sometimes less).  Didn't use to have this issue: I've updated to the most recent operating system and the most recent Spotify update, but it doesn't seem to make a difference.  Ready to give up.

Are you in offline mode when listening on your iPad?

Any chance another user is logged into your account and listening on another device?

Hi: no to both questions (no one else uses my account and I listen online).

Only happening on iPad? Not on any other device?
