Lookout Security Extension uses a VPN service to function correctly. Android allows one VPN to be active at a time so Lookout will turn off your other service. This way you can continue using the Lookout Security Extension app and Safe Browsing feature.
Click “continue” to turn off the existing VPN and enable Safe Browsing.
If you prefer to use your own VPN service, please turn off Safe Browsing within the Settings menu of the Lookout app.
