Since installing the VPN app on my LG V20, the VPN app has a peculiar behavior. If I launch the app for any length of time longer than an hour, then the app will refuse to stay closed. For example, I travel to a hotel and use the hotel WiFi. I launch the app and enable it. I use it for 2 hours, and shut the app down. The app will relaunch automatically after anywhere to a couple of seconds later to several hours, depending. The app icon will appear in the upper left hand corner of the screen, but will not be listed as running apps that can be killed. I have to relaunch the app and then kill it for the icon to disappear.
