I am currently working on the migrations from ArcMap to ArcGIS Pro.
I used "Apply Visual Specification to Map" geoprocessing tool to import the vst used in ArcMap into ArcGIS Pro. After that, I could see that the symbols were set the same as one I used in ArcMap. I found that the vst was translated into arcade for symbology.
I wanted to modify the arcade applied to each feature classes like adding and deleting symbol class. However, every time I modify the arcade, the symbol classes only show the one with data.
For example, before I modify the arcade it showed all the symbol classes vst offers.
But after I modified the arcade expression, it only shows the symbol classes that own the data.
So, I'd like to know if there's a way to keep the original symbol classes and add/delete the class as written in arcade expression.
