Notification on notification bar disappears

[camillo75]

Hi

I have a Samsung Galaxy Note 3 with Android 4.4.2 and I am playing with Spotify connect on a Denon avr. 

When I start playing,  I have page Spotify notification of current song playing. 

After some time the notification disappears. 

Do not know why,  if it is made by design or is it a bug,  or the application in the background crashes or closes itself after some time. 

You can see that I have also Sonos and the Sonos app stay in the notification bar forever as it should be. 

This is annoying because I have to search again for the app to open it if I want to change song or change volume. 

Any idea? 

I attach 2 screenshots, after pressing play and after a while. 

The sonos app is always there but Spotify no. 

Thank you

Camillo

Unfortunately that's Android closing the process as part of it's power saving scheme. It annoys me also, but it's not a Spotify issue.

But Sonos notification stay there forever.
App can be closed by os but the notification is not linked to the app can live forever.
