If you are navigating in online mode and the internet connection is lost, the app will continue trying to connect with the internet. If the app fails to reconnect to the internet, stop your current navigation and start a new one in offline mode. 

To use the offline navigation of WeGo, switch to offline mode using the toggle in the app’s settings. If the toggle is off, the offline navigation won’t work as expected.

It’s also important to make sure you previously downloaded the offline maps of the regions you’d like to navigate through.
