Why can't I see Kill Switch on my iOS/macOS device?

On iOS and macOS, Kill Switch is currently available only with the IKEv2 protocol. If a different protocol is chosen, you just won’t see the Kill Switch option in the settings. So, to use Kill Switch on your iOS/macOS, follow the below steps: Make sure the chosen protocol is IKEv2. For this, go to the app Menu Settings Protocols. Enable Kill Switch, which you should now be able to see in Settings.
