Nathan,
When we created Site Scan, we realized that there was a need for a free, disconnected, app for Drone2Map users. We created Site Scan Esri Edition, now Site Scan Limited Edition, to fit the bill. From a developer's perspective, these two apps are identical save for a flag that limits LE from connecting to the Site Scan cloud (for processing, flight plan sharing, and fleet management). Thus when Site Scan updates, LE will update either at the same time, or with a two week delay due to additional testing.
I have verified that both Site Scan and Site Scan LE are running version 4.0 which is the latest version. If your LE app is not showing the features listed in the 4.0 update, please check to ensure that the app is up-to-date in the app store. If you're seeing inconsistencies let us know and we'll look into it!
