if have an installation with ArcGIS Portal and ArcGIS Server 10.6. I uploaded a Server Object Extension and Server Object Interceptor to the ArcGIS Server.
When I create an mxd file with ArcMap and publish a map service from ArcMap, I can activate the SOE as well as the SOI on this map service in the ArcGIS Server Manager.
When I publish a Map Service from ArcGIS Pro, it is not possible to activate the SOE or SOI for the resulting map service in the ArcGIS Server Manager. I don't even the SOE or SOI in the configuration page of the map service.
Can anybody give me a hint what's wrong?
