The web service is in WGS_1984 and I have set the default extent of the WebMap to that of the WMS imagery. When I add the WMS Service Imagery as a layer it displays correctly, however when I try to explicitly add it as a basemap, the imagery appears distorted and doesn't display in the WebApp. Is this an issue with WMS Web Service not being able to be used as a basemap? First time using a WMS Service in Portal so I don't know where to go from here. I attached a screenshot as an example of one of the ways it displays when I try to use as a basemap. Anything helps, thanks.
