I haven't tried it in about 6 months using whatever version was packaged with Ubuntu 22.04. My configuration was basically the same as yours. systemd-networkd seemed to always be a moving target as far as configuration syntax but mine was mostly the same as yours syntactically and functionally the same. It is mute now. I deployed a new Ubiquiti network including cameras about 6 months ago resulting in the linux router/firewall being replaced with a Dream Machine Pro.
