I'm using a static route to a remote network through a wireguard tunnel, and since I migrated to 26.7, it does not survive a reboot.
The entry is still there but I have to manually click on "Apply" ever time after boot for it to work.

I migrated from 25.7 and everything was fine then.
Why don't you add that network to the AllowedIPs of your WG peer? WG will set up the route for you, then.
It was just the way I was comfortable managing routes. Anyway, that worked so I will stick to this method.
Thank you for you help!
