@FredericPoliart_EsriAU Thanks for the feedback. In my case I think it might be a little of all that you mentioned. I'm working on a disconnected network so our systems do not get updated as quickly as most. The system that has the most recent version of ArcGIS Enterprise is at v11.1. I'm mostly interested in leveraging an external Feature Layer service within Experience Builder. When I add a connection to the service via URL connection in the "Add Data" component of Experience Builder it sees the service and exposes the layers within it. The map widget doesn't recognize these layers as a supported data type. So, what widgets within Experience Builder will allow me to add these feature layers as an overlay within the Map view, and toggle the layer visibility (similar to those that are added via web map)? It seems counterintuitive to have to mask the feature service within a Web Map service.
