I am having an issue with using hollow/no fill polygons through a feature service being consumed in the ArcGIS for iOS app. They display fine in the ArcGIS.com viewer, but in the iOS app they are shown with a black fill. If I create a map on ArcGIS.com pointing to the MapServer REST endpoint of the service then the polygons show up correctly with no fill, so it appears to be related to polygons pointing to the FeatureServer REST endpoint. Also tried using transparency and that does not seem to be supported in the ArcGIS for iOS app.
I am not finding any other information or posts regarding this, has anyone else ran into this?
Thanks,
Josh
