The Zubie device has to acquire a GPS signal in order to share your location. It’s possible that the GPS signal is blocked somehow. GPS signals and accuracy can be impacted by building structures such as high-rises, parking garages, or underground parking.
Another reason for this is network coverage for the area you are driving in. When you drive into an area with poor coverage the first few GPS points can go missing, due to lack of network connectivity. This should be resolved once you enter an area with good network coverage.
