Adding AOI as a feature layer to map or zooming to it from the Order Dashboard doesn't show the feature on the map.
Before ordering new imagery and drawing your own AOI, it is highly recommended that you save and close out any editing sessions you are currently performing on vector data, as this tool will automatically save any open edit sessions.
Drawing an AOI using the AddIn's Draw tool, and then drawing another AOI that's much larger will produce a bug where the 2nd AOI doesn't appear on the map
Remove the EarthCache User AOI Layer from the Table of Contents and from the default Geodatabase. Then, draw the AOI again on the map.
