Apparently, when given the same Lat/Lon position, Mapbox and Google Maps disagree. This wouldn’t be an issue except for the fact that when you click on the Mapbox, you shift over to Google Maps. Since I use MyMaps to find Lat/Lon positions, the Mapbox positioning looks wrong to me. Examples:
Mapbox:
Google Maps:
With Mapbox, the position seems to be at the dot of the Mappin, whereas in Google Maps, the position is at the point of the pin.
Not entirely sure there is anything to do about this, but just thought I’d mention this.
