MT300N-V2 upgrade 3.212 VPN Led

I just upgraded my firmware to 3.212.
The middle LED no longer shows wg0 connection and activity.
I checked the setup and it still shows the configuration.
Actual VPN switch works properly.
Is this a bug, or do I need to modify a setting?
Thank you.

Install Luci, go to system->LED configuration, edit the LED for wan and change it to wg0

I previously checked that. Also, I confirmed that the VPN is activated and working.

I just tried exactly the same.

The LED indicate wireguard correctly.

I only need to reboot the router to let it take effect after settings.
