Hi @Guv999, welcome to the Sonos Community!
I’ve had a look into our system and found your case and chat with our support team.
From what I can see, a few steps were tried to have your Connect:Amp to the newest version, but this wasn’t successful so you were requested to call our support team for a remote session.
Because of the nature of this issue, there isn’t much we can offer in the way of troubleshooting and other users of the Sonos Community will not be able to resolve this.
I’d suggest reaching out to our support team again via the information found on our contact page, then providing them with your case number or email address to continue where the chat agent left off.
I hope this information helps!
