The structural symbols I defined on the feature classes are rotated and display correctly on my Webmap after publishing my map document to Portal for ArcGIS.
However when the map is opened in Collector, these symbols on the feature layer loose their rotation.
This issue is very important to our organization's field geological mapping workflow. Is there a workaround this problem? If not, are there plans to incorporate this in the new Collector Aurora update slated for 2018 Q2?
