Is there any update on the support for Alexa multiroom music (MRM) support on Sonos? I just purchased a Sonos Beam with the understanding that it supported Alexa groups. I learned after setting it up, that while it can be added to an Alexa group, it can’t be added to a speaker group with Echo devices. I understand that Amazon released the software to implement multiroom music support in 2018 (link below) and that at least the Polk Command Bar supports this functionality. Is there any possibility that Sonos will add this capability to the Beam? If not, I’ll need to return the Beam and find another solution.

I'm not aware of any multi room speakers that are compliant. The issue remains that Amazon and Sonos both use their own proprietary multi room buffering technology.
