Hi,
I am working on a Web Map in Portal for ArcGIS and am currently having issues with the legend not displaying points correctly. I have published the service and although the symbology displays correctly (coloured), the points appear in the legend as small grey dots. The polygon features shared in this service are displayed in the legend fine, it is only the points which are causing issues. I have tried republishing the service and adjusting the symbols different ways but this has not changed the legend within Portal whatsoever. The points have been displayed using dot density within ArcMap.
Here are a couple of screenshots of the legend and map within portal, and the legend in ArcMap (as it should show).


Any help would be much appreciated.
Cheers,
Kieran
