In QGIS 3.22.0 (Bialowieza) I have a polygon layer of municipalities in Germany. Some municipalities consist of more than one polygon. I have duplicated the layer in order to make a categorization of a value within the layer. The categorization is displayed as a point-symbol.
My problem is that the municipalities with more than one polygon also show more than one point-symbol (attached image). How can I reduce the number of points and have the point only displayed in the largest polygon. (The municipality of Konstanz consists of three polygons.)
