Sonos with Alexa. Device Settings showing Red Banner 'Device Offline' with stale address

I’ve been fighting this for days. Any thoughts appreciated.

• I have 2 places with Sonos groups, 1 of which was a move from Location A to Location B
• Separate Alexa accounts for each group to accommodate the Alexa commands to the Specific Sonos devices for that location

2 interesting findings.

#1. The Sonos devices are listed 2x, once as the Alexa device, and once as the Sonos device. Attachment 1

#2. I cannot get rid of the Red Banner at the top of the Sonos Devices, AND the address is an old Amazon Alexa address, my earlier location. Attachment 2

Troubleshooting:

1. I have deregistered on the Alexa app
2. Deregistered on the Amazon Store (Devices List)
3. The old address doesnt exist anywhere
4. Removed and reenabled Skill (Sonos)
5. Rebooted device, router
6. Contacted Amazon and Sonos support.

I can’t figure it out. Any help would be appreciated.
