I am creating a web map for disconnected editing with sync enabled in the collector app. I have realized that having a hosted aerial tile layer as a basemap with other hosted feature layers is not supported for offline use. How do I make my web map available for disconnected editing using my own aerials? A tile package layer is an option to load locally on the device, but my map is still unavailable for download with all other feature layers available for offline use. Can I remove the tile layer basemap in the existing map and how?, download the map in collector, and use locally stored basemap?
