I am building an ArcGIS online map showing RSEI facilities and Census Block Groups. Both appear to be map layers (the RSEI facilities layer does not seem to be a feature layer). I can't get the RSEI facilities layer to layer above the census layer so that the RSEI facilities show on top of the census layer. I can't move the RSEI layer above the census layer. And, I can't move the census layer to basemap. Any suggestions?
