Hi @damas.
Thanks for reaching out and sorry to know about the experience. Let me help you and try to figure out what’s going on.
If I understand it correctly only one of your Sonos components is working and the rest are not?
Are they missing from the system?
What specifically is happening when they are not working?
Kindly submit a diagnostic report through the Sonos app when the issue occurs, and reply with the confirmation number. I'd start by reviewing your system, it will help in identifying what's possibly causing the issue.
I’m looking forward to assisting you further from here.
If you have any other questions or run into any issues, please do not hesitate to reach out, we are always here to help.
