Sophos Firewall: v18.5 MR2: Feedback and experiences

I just tried to manage a Sophos XGS116 with the OTP token. But it wont give me the expected popup in the Sophos Central portal according to the article Use OTP to turn on Central management - Sophos (XG) Firewall

If i enter the serial number it gives me the following tekst: If your firewall is already deployed and configured, you can join it to Sophos Central for management from your Firewall WebAdmin. Please note that a firewall can be managed at any point of time either via Sophos Central or Sophos Firewall Manager (SFM).

So i'm not able to create a OTP token for the firewall.

Is there something i'm doing wrong?

This should the process. Could be currently still disabled in Central itself, i would recommend to try this tomorrow, if the process will be shown. 

Here you can see the process: https://www.youtube.com/watch?v=Gkxg9nRy1dQ

Thanks
