Have a way to quickly see and send notifications to people who are using the outdated / non-current ipad app.
Today for Buzzsaw you have the ability to restrict how far back users can be in software releases for the product.
Autodesk continues to publish updates to the app - there are probably items not completely / fully described in the itunes store update that improve the app and overall suite performance so it is very important that all the users are on the current software release.
In doc's maybe the sync won't occur if you aren't at least 1 app update back......have a notification that comes up.
