I have created a Sonos Play list from tracks in Deezer and other sources.  The Playlist is set to the order i enter the tracks.  How do I change the order in the play list.

I have tried to do this whilst a track is playing.  Sonos accepts the change but will no make the change permanent.  I have gone through the /end save.

Can anyone tell me how to make permanent change to the Sonos Play List.

Please!
