Openvpn route-up and route-pre-down broken in 23.05

Hi - I had to setup a new server due to expired certificates. I upgraded to 23.05 and followed this guide: https://openwrt.org/docs/guide-user/services/vpn/openvpn/server

I can login to the VPN, but none of the internet / routing is working. Will this patch fix that, or do we need to update the official guide?
