I have a tile layer that I have uploaded from ArcMap to my AGOL account (with 17 layers of detail), and have published it so that it can be added to an online map. However, nothing appears when I try to open the map. Only the topographic basemap shows. The tile layer is of a raster, old aerial maps. I found another thread on here that suggested going to Layer Properties > Data Frame in ArcMap and checking "Extent of data in all layers (default)". However, when I went there, it was already checked off. So, now I am unsure what is causing my tile layer not show. Any ideas would be much appreciated.
