After I followed instructions from several different threads trying to check all of the basic things (no duplicate names, all user profile info is filled out accurately, etc) the next step was to disable and re-enable the sonos skill which is where I've hit a wall. Now Alexa and my sonos system no longer integrate. Sonos is otherwise fully functional and works fine with my other music services and TV.
The sonos skill will not enable and tells me "You need to link speakers to firstname.lastname@example.org before you can add this skill". Of course my speakers are already linked to the account because it's fully functional, but I still logged into my sonos account and confirmed the email address, password, home address, etc., and I went into the sonos app and "forgot" any sonos devices, powered them all down, powered up the wired one first (playbar), and then powered up the rest. I even tried transferring my sonos account to the same email address just to try it, but I still get the same frustrating message (asking me to link my already linked speakers). Not sure where to go from here (fyi, I am desperately trying to avoid "forgetting all devices" in my alexa app, or deleting the alexa app because I use it to control a bunch of other devices in my house and I'm not looking to throw a grenade into this already opened can of worms). Any direction would be greatly appreciated.
