I created a web map in our organization AGOL. I applied Heat Map style to one of the layers in my web map. I turned this heat map layer on and hit print. The printed image included the heat map. I went back to my web map and turned the heat map layer off. I hit print again, my printed image was still showing the heat map layer despite the fact it was turned off!
The same issue persists if I create a web app in WebApp builder and use either the default printing service or our own.
I'm not sure how the printing task deals with this type of layer. Anyone could please help?
