I have Private Internet Access VPN, and have been connecting using their own app. I have set the app to connect on system start up, app start up, etc., however there are times when I catch the VPN disconnected.

There is a Killswitch setting within the app, however it instructs you to use the built in Android feature, which doesn’t appear to exist anymore.

Other than setting up a VPN connection on the router, how else do you all ensure all traffic is routed through a VPN connection?
