The issue I am having is that after the FeatureLayer is displayed on my Web AppBuilder map, I an unable to select it using the Select Widget unlike other MapService layers (that are comprised of shapefiles - see screenshot below). Any information on why this is the case and how to make the FeatureLayer selectable would be helpful.
FeatureLayer on the web map:
FeatureLayer (Smaller Scale):
Screenshot showing that FeatureLayer is not selected by the Select Tool unlike other shapefile mapservices (blacked out FeatureLayer shows "0" selected features):
Select Widget Config (apologizes for the low res image):
