Your device failed to be claimed

I had a stand alone Argon unclaimed and when claiming to set up a mesh network via iPhone 7 Plus app, the Argon connects to the cloud again, but it ends with a message on the iPhone “Error Your device failed to be claimed. Please try again”. The device does not appear in the console.

I have tried again also with the phone power cycled, with same error. Is this related to the recent announcement about cancelling mesh or is this a thing for support?

I thought a year after I shelved the Xenons, it should be possible to set them up without bug reporting. I will trash the 5 xenons - problem solved.
