I am learning how to use ArcGIS Online and Collector for ArcGIS. I have created an ArcGIS online map. It is properly configured to use in Collector. I can access the map on a mobile device, which is running Windows 10. An attempt to download the map, for unconnected use on the mobile device, will not work because the Download button is always greyed out.
Why is the download button greyed out? What could I be doing wrong?
More info: a help flyout on Collector says to do two things: pan and zoom to the work area; zoom to the map detail. Then press download when ready. That makes no sense, as there is no way to tell the system that you have completed the two steps. I can pan and zoom, all day long, but nothing enables the download button.
