costumers travelling to China with our GPS-app (based on the Here-maps-control) are reporting, that their position is displayed wrong on the map (about 300m shifted)
The funny thing is, when they check on the WP8-Here-Maps-App, which is using the same maps, the position is displayed correctly.

How is this possible?
Is there a correction to this "China-Shift" build in the Maps-app, which is missing in the Maps-Control?
