Steps to Reproduce:
Choose any city that has the feature to display a city on the map of the country, e.g. Munich in the German version. (London on the other hand doesn't have this feature)
Chosse to display the mobile site instead of the desktop site.
From my tests, this issue arises across multiple devices, operating systems and browser versions.
The city location marked with the red spot is further to the south-east than expected
The red spot should be the same as on the desktop site
