Is it possible in QGIS 3.16 to use the geoprocessing tool "Difference" with point layers as input and overlay?
The documentation seems to indicate that it is. However, when I do a test with very simple layers, it gives a GEOS geoprocessing error:
difference failed
The input layer has 10 points, and the overlay has 6 points - these 6 points are in the exact same location as 6 points in the input layer.
