I’ve had the Sonos system running for years. I’ve had the Move attached for a long time as well.
This morning, the Move was not showing up in the app. After doing a Factory Reset and going through the Add Product process, I get the error message listed in my subject line “There was a problem setting up your Sonos Move. Our Customer Care team is ready to help”.
The Move is still listed under System as Sonos Move, Not registered.
I have gone through the Factory Reset process several times, with this same result.
