NetworkManager snap not setting route-metric

Hi all,

Probably a question/bug for the NetworkManager snap maintainers. Why can’t I set the route metric for my connection profiles anymore? I can set IP addresses and whatnot, but not route-metrics?

Been running Core20, and network-manager from the 20/stable branch, version 1.22.10-23, also happening on the normal Ethernet connections too. Reference below:

As for the NetworkManager logs, there’s no indicator that there’s an error or something. Using the command:

sudo nmcli con mod "Wired connection 1" ipv4.route-metric '10'

Journalctl log:
