On your client device map you may notice a city or district in the wrong location and/or moving around the map as you scroll or move.
This happens when a few roads, a long way apart, are labelled with this city name. It usually occurs when an area is first being mapped. A few major, long roads will be assigned the name of the nearest city.
Once a handful of city streets are mapped with the city name the location of the displayed city name will become fixed on the correct location.
