Current issue: In ArcGIS Pro, we have created some groups and sub groups. After publishing hosted feature layers to the ArcGIS enterprise portal, we cannot see the groups and the sub groups on map viewer.
If we publish hosted map image layers to the ArcGIS enterprise portal, we can see the organized groups and sub-groups as we had set in ArcGIS Pro. However, it is only limited to map image layers but doesn't work for feature service layers. I hope this could work for feature service layers.
