I tested the geometryEngine.intersect with two polygons. One has the purple boundary and the other one has the blue fill. So, when you run the intersect the red line shows the results. If the intersect was working properly, since the blue fill polygon is inside the purple polygon, the intersect (red line) should run along the the contour of the blue fill. It seems that it follows some vertices. This is an issue since the area of the intersect will be miscalculated. Ideas? Thanks.
