My Question or Issue

I am developing an app that uses Spotify SDK to obtain currently playing playlists. 

I have a button that redirects user to Spotify app, to select music, and when the user returns, SDK provides the current context of the user. 
My problem is that after SDK connects to Spotify, AppRemote

disconnects after a few minutes. And I have to reconnect at each button tap. 
Is there any way to SDK stays connected to Spotify ?
