I have the same problem. On a freshly installed OPNSense 26.7, the automatic route isn't set either.
If you try to set it manually via the GUI, the following message appears in the log (even though the "Tunnel address" field isn't empty):
ROUTING: refusing to set interface route on addressless opt1(wg0)
My workaround so far is the following command via the shell:
route add -net 192.168.1.0/24 -interface wg0
But this only lasts until the next service or firewall restart.
Even an update to version 26.7.7 didn't fix the problem.
Maybe this information will be helpful.
