Update XG firmware installed on own hardware?

Hello,

First, thank you for providing Sophos XG Firewall to home users to install on their own hardware. This is a nice product, and I'm appreciating the advanced feature set (was using pfSense previously).

My question is how should users who have installed XG on their own hardware update the firmware?

When I check this in Administration --> Firmware, it does not show the available updates. (e.g. I'm currently running SFOS 17.1.3 MR-3 and I see that SFOS 17.1.4 MR-4 should now be available)

I do not see any firmware updates available in the My Sophos portal.

I have read https://community.sophos.com/kb/en-us/123285

Thank you much,

Ari
