Im trying to add my Drone Deploy imagery service to my autocad project. I have added and shared the WMTS to my organization in my esri portal. I can see it in the portal as well as Pro and in arcmap. When I search for the service in the arcgis to autocad 400 plug in it cannot find it. I have also tried to just add the specified URL with no luck. Can the plug in not handle a WMTS service? can it only work with a WMS service?
