I am trying to use two Tiled Map Services as a basemap for use in ArcGIS Online and Web App Builder.
I am able to do this fine in Web App Builder, as the basemap widget allows you two add two services or more when adding a new basemap
However, I can not figure out how to get this basemap to be recognised by my organisation's basemap group in AGOL, and be selectable as a basemap when setting up the Web Map on ArcGIS online. I want this two service basemap to be the default on my web map when opening the application, so it needs to be recognised in ArcGIS online.
Has anyone had any luck with multiple service basemaps in ArcGIS online. Any help would be much appreciated.
