When I posted a dataset of wind force and direction in ArcGIS Pro 2.1, I was surprised _not_ to find an arrow symbol. When I styled it using an SVG file as indicated in Esri Help, it post well in a 2D Map & 3D Scene in Desktop. When I publish it to a Web Scene, however, the symbol set I created from SVG is fuzzy, whereas original Esri symbols are OK.
Am I missing something or is this a bug?
