Still Installaltion stage

[agent_kith]

I have a paid edition, and hit "save" then I cannot find the Snakeoil "device" on my smartphone(with spotify connect) or laptop(with spotify connect), how do I find the Snakeoil device? 

It's activated, not paid. :p Semantics but important nonetheless.

I have not try Spotify myself.

But you probably need to VNC into your Snakeoil PC, once in, you'll see a Spotify connect GUI loaded in this virtual desktop. Follow the spotify instructions to set things up, and then see if your client can see it afterwards.
