I recently switched from Desktop to Pro and totally at a loss of figuring out how to make this very simple script work in ArcPro. Note that it runs and says success but the symbology does not change.
import arcpy
in_fc = arcpy.GetParameterAsText(0)
in_lyrx = arcpy.GetParameterAsText(1)
arcpy.management.ApplySymbologyFromLayer(in_fc,in_lyrx)
