Internet killswitch

3.100 was just released on stable firmware for my device and I am confused about the kill switch.

In the VPN section it states that internet will not leak while VPN is configured. So what is the point of the new killswitch setting - what else does this do?

I was under the impression that with VPN on (even if unable to connect) there would be no leaks (as stated in the the VPN section).

Now I am wondering if the effects are not correctly labelled in enhlish

For example, it stops IP leaks when you wish to switch servers from VPN > Wireguard (or vice-versa), which necessitates disconnecting, then reconnecting.

IMO, the old manual kill-switch was far superior to the dummies auto-kill function, so the new re-appearance in the latest firmware is very welcome!
