Question

 

ESRI dynamic labeling is server side labeling, which means the label was generated on arcgis server before send to you.

ESRI dynamic labeling test use 17, 170, 171, 270, 271, 

Note:  Original ArcPro project must use Maplex label engine. Standard label engine would not work.

Client side labeling means the label is not generated on arcgis server, instead the label is generated in your browser.
