With the 4.8 API, labeling is now available for points and polygons. I have 10.6.1 installed, webGL enabled, and am consuming a point and polygon feature class as feature layers. The point layer labels just fine, but the polygon layer does not. Am I missing something? I even manually added a labelClass for the polygon layer and it still doesn't work. I can't find any examples of polygons being labeled online with the 4.8 API. Any help is appreciated.
