Why is your location displayed incorrectly or not at all on the map of the area?

If your location cannot be found, it’s usually because we still need you to give your authorisation that we can locate you, or because the location services on your smartphone are deactivated. A reliable service can only be guaranteed if the hvv switch app has permanent access to your location. You can provide your authorisation the first time you use the app, or alternatively do this at a later stage directly in the settings of your smartphone. You may also encounter problems however if there are walls, vehicle roofs, tall buildings and other obstacles temporarily blocking the GPS satellites.
