Toggle switch doesn't do anything on Mango GL-MT300N-V2

Hello there everyone.

I've recently purchased that wonderful tiny mango thing and everything works fine except one annoying issue: the toggle switch doesn't turn on/off the VPN client.

I set a Wireguard one and the tunnel itself works fine, but I am unable to turn it on and off with the button switch on the side of the router.

I am using the latest 4.3.11 firmware and was checking if the button works at all via ssh, so I am getting changes LO/HI when I change its position:

root@GL-MT300N-V2:~# cat /etc/glversion 
root@GL-MT300N-V2:~# cat /sys/kernel/debug/gpio |grep switch
 gpio-480 (                    |switch              ) in  hi IRQ 
root@GL-MT300N-V2:~# cat /sys/kernel/debug/gpio |grep switch
 gpio-480 (                    |switch              ) in  lo IRQ 

is there any way to fix it?

Have you enabled the switch in the user interface?

I set its action to "Wireguard On" in that toggle button settings, if you mean that.
