There is a severe bug in the new Sonos beta relating to volume control via Alexa. Attempting to use Alexa to increase or decrease volume on a Sonos player/room by a specific increment (e.g. "Alexa, reduce volume in the Office by 10%") creates two problems.



First, Alexa returns an error response, saying something like "Office does not support that command" - annoying, but not a big deal in a v1 beta.



The much larger problem is that the Sonos player/room in question subsequently drops off the Sonos controller app, making it impossible to use. I've tried soft reboots and hard resets, but neither solves the problem. The players that have been impacted are just gone.



That is obviously extremely frustrating. Sonos moderators - any idea how to fix?
