Appleid.apple.com will not let me add a trusted number (have done before)
Previously adding a trusted number in appleid.apple.com, account security, as here

This is a completely new message, and if I follow the instructions there is nothing in the other device to allow me to add the new number.
Apple status website shows all green today.
