The Poly and 2go are slightly different. I only noticed when I changed Poly to 2go. You have to select Roon or Everything else on the Poly but the 2go just had automatic.
With both I used Mconnect. There is a free version but for a fiver or so I got the full version. Once set up it’s pretty seamless and streams hi res quite happily. You log into Qobuz from the Mconnect app so all you playlists a favourites etc are there but I don’t believe there is any way of streaming direct from the qobuz app.
Fantastic, thank you. I was able to get going with the Mconnect app. It’s not quite as good as the Qobuz app but at least I’m streaming in high res now. No reason I can’t switch back and forth.
