After projecting my imagery to match the Topo layer's projection in ArcGIS Online, I went through the steps to again publish it. It still won't lay on top of the Topo map layer. When I try to place it in a map with an Imagery basemap layer I receive:
The imagery basemap layer is in the same projection (3857 - WGS_1984_Web_Mercator_Auxiliary_Sphere). There must be something else preventing this from publishing properly. Any ideas?
