Alexa breaking groups (yet again)

I came back from holiday to find that once again Alexa breaks my Sonos groups (third or fourth time). I have 5 Sonos speakers grouped through Sonos (group created from ‘Living Room’ paired speakers). I also have the same speakers selected as preferred speakers under the Alexa group ‘Living Room’. However if I tell Alexa to ‘play music in the living room’ it only plays through one speaker (bizarrely one named ‘Dining room’ although it is part of the group) and if I go into the Sonos app the group is broken. If I just tell Alexa to ‘play music’ then it only plays through the Alexa device (so the preferred speaker setting is meaningless?)

So far I have checked for an update (there are none), renamed the living room speakers in case there is a conflict, disabled and reenabled the Sonos skill, rerun device discovery (after every change), set the living room speaker as the only preferred speaker (which then works through Alexa) but any Sonos group created is still broken by Alexa. Basically I’ve trawled the forums trying everything I can find to no avail.


I’m going to totally uninstall and reinstall Sonos to see if that works but I'm really getting fed up of having to constantly fix stuff because Alexa and Sonos want to ‘improve the user experience ‘ which adds nothing but breaks everything. I think the app developers just need to justify their salaries. I’m reasonably tech savvy but god forbid if I ever kick the bucket because there is no hope in hell that my wife will ever be able to use this stuff. I’ve now reached the point where I’ve given up on Sonos.
