So I figured that if there was some consistency between the symbology you find across all the Esri platforms, it would would help streamline some processes and shouldn't be too difficult to pull off. For example, one of the Crime Analysts where I work was trying to perform some analysis in ArcGIS Pro instead of Portal due to some issues in Portal. However, when it came time to create and share her map, the symbology she used for a certain feature;
only exists on Portal for ArcGIS or AGOL (minus a convoluted workaround). I searched for the AGOL symbology to import into Pro to no avail. Let make a style file (stylx) of these!
