Rarely, since when the location is (as it should be) historic and not current, Google Maps will not find it.
When I want to find where a place is, I google it to find out the current location, and when I have it use Google Maps.
I hoped there was a quicker way by adding the current location in a category, but apparently the new fashion is to use historic location categories as well, so even that won't work anymore.
To clarify, I want the locations in the data fields to stay historic, so I don't see the point of having the map pin there for old profiles. I would like the map pin to be used near a location that works with it. That should be the subject of a Suggestion thread.
