Can I still manage my Sophos Free Home Firewall after 30 days trial period?

Question

Hi, 
 I had install SFOS on my own old PC for some time, but did not connect /join Sophos Central after more then 30 days. 
 I was trying out DNS protection after watching this video from Sophos Techvids: https://techvids.sophos.com/watch/YKKJiTqRndLS1eKRKsdJqe 
 Little do I know that, I cannot claim my Sophos Free Home Firewall within Sophos Central after entering the serial number, 
 and hence I cannot add into Sophos Central. As result I cannot try out the DNS protection. 
 In order to try it out, do I need to pay a subscription? 
 Thank you.

Let me specify: Claim/Registration for a license is not possible with Home. 
 Management is possible for home. You have to use the account credentials. Home does not support OTP Process. 
 The point here is: SFOS Home is simply excluded by the "license process" and OTP tries to claim the firewall, which is not working. It is a "known issue".

Sophos Home will generate a Serialnumber for you, which you have to use. You do not claim / register this SN in Sophos Central.
If you start a Trial in the installation process, this will start a Sophos SFOS Business version. You cannot change from Business to Home or vice versa. You have to reinstall the firewall.
After using your Sophos Home Serialnumber, you can restore your backup.

Finally, after searching 1 whole day. I managed to connected my Sophos Firewall Home to Sophos Central. 
 I went in to My Products > Firewall Management > Firewall > go to right side, look for the icon: > 
 The ">" is the icon I need to press to see my firewall which is waiting for approval.

They are the same thing. XG/XGS is the product name for Sophos hardware where you load Sophos XG software to, the same (not quite) software you load onto your own hardware.
