1) I have a Portal stack. My ArcGIS Servers are federated to the Portal.
2) I can publish a Map Image Layer from ArcMap to the standard ArcGIS Server publisher connection (e.g. https://domain.com/arcgis/admin) which contains group layers, and groups of group layers. In this case, 232 layers sensibly sorted into groups.
3) If i try and publish the same service from ArcGIS Pro, the group layers are ungrouped, and all 232 layers are published in the map image service ungrouped.
Does anybody know why? How do we get group layers back in Pro?
10.8 Portal, 2.5.0 Pro.
