If you are using an Android device please check your location setting and select GPS, Wi-Fi, and Mobile networks. If it's GPS only than it will not work. Also to test this I would recommend doing this at home and log out from the App and log back in then drive about a couple blocks away (approximate 150 ft) and drive back toward your house. If you are still having issues please let us know.
