Hey @DuD, welcome to the community.
How are you able to connect the Move to Airplay if it’s not connected to your network? Are you able to see the Move in the Sonos app when you’re connected to Airplay? If so, I recommend submitting another diagnostic report and sending the number over to our Customer Care team who will be able to take a closer look at it with you and work to find a solution. 
By the magic that is wifi and internet I am now back up and running! I switched off both wifi and iMac, the Move was then “seen” as not having been registered! One click, one “bong” and it’s back in the room! I really have no idea what has changed to did change. I now have a fully functioning Move and Sonos system within the App and on Airplay, with Apple Music and Spotify all woking correctly. I didn’t even get a chance to submit another diagnostic report. Thanks.
Great! Happy to hear it’s all working again 
Thanks for following up!
