That's what made me ditch sonos 4 years ago. Being forced to run everything through the awful Sonos app instead of casting from the dedicated app or playing through Bluetooth without any delays.

Last I checked, the Sonos app is better than the SiriusXM app. Not that I use it much anyway, I mostly use Sonos/Sirius via Alexa control.

What do you use now? Seems to me like the only decent solution is UPnP.
