Play music on Sonos from Deezer App

I'm finding the Deezer "Plug in" to my Sonos ap difficult to use. I don't appear to be able to find new things and play them from there. I also can't find them in the normal Deezer app and "send" them to sonos. I have to find them in Deezer, set them as favourite, then go in to Sonos to play them. This is unwieldly. It also appears that you can not mark a "Mix" as a favourite meaning I can't play a mix through my Sonos. Any help available??
