cloud dns problem

Hello.
I have a problem, I can’t figure out how to solve it.
CLOUD DNS is not working. the field where the public address should be specified is empty, DNS NAME is empty. The device is RB2011.
Help me understand what the problem is and fix it.

Hi, I’m having the exact same problem with my RB1100. It’s updated to the latest version (7.19.1).

Have you managed to fix it or does anyone know how?
