I have the last version of lightroom classic as of spetember 2021.
I was looking at the map of my photos when I realized some photos were not assigned at the right location so I started to move them. But the more I did the more there were photos that were assigned stupid location. I was only moving photos that were single (not clustered with other nearby photos so no error on that point). And I remebered for someof them that the location they had befor was ok. Finally I started to find photos on the map that did not even have GPS coodinates! They were randomly placed on the map. Thats when I realized that lightroom do not respect the cooordinates!!! So I opened 3 different other software using different metadata api and all of them showed the photos in the correct location. I lightroom the error ranges from a few meters to several thousand kilometers. (and it is not a question of cluster and zoom level). So this module is unasable for me, but also I regret having trust it since correctly placed photos were moved by trusting lightroom.
when trying to manually position a photo on the map, the photo is not located at the point I dragged it to, but further to the right and further down. The displacement is always constant, measured in mm on my screen, no matter what resolution the underlying map is in.
@RRFfm - That's a long standing problem on high res/high DPI monitors. The work around is to right-click on the map location and choose "Add GPS Coordinates to Selected Photos" instead of using drag and drop.
