No you can’t add a service that’s not listed, but maybe contact the Presto music service staff and perhaps suggest they add it to the Sonos eco-system instead. If it’s viable for them to do that, they can then approach Sonos themselves.

In the meantime there’s Qobuz.

Alternatively use the Presto native app and send the audio to Sonos. On Apple this could be over AirPlay. On Android one could use Bluetooth, but with an obvious quality compromise. Sonos doesn’t support Chromecast.

Thank you for the information. I’ll contact Presto Music. I don’t understand what you mean by Sonos eco-system though. I hope they do. 

I think I will try to use the Android Bluetooth and see what happens. I didn’t think of that. 

Your profile lists Roam and Move. Target the Roam with your Bluetooth and then group the Move with it if you want to play on both. Roam can receive Bluetooth and participate in the Sonos system at the same time. Move Gen 1 can’t do this; it’s one or the other. (Move Gen 2 addresses this shortcoming.)

Just point them to https://devdocs.sonos.com/docs

Thank you for the link. 

Any luck?  

I submitted the link to customer support who, in turn, submitted it to their tech support. They said they’d look into it. Thank you for asking. 

I hope they follow through with it because they are an excellent resource for classical and jazz music.

I agree. I wish they had Atmos or surround content, etc, but Sonos support would be even more important.
