I'm using ArcGIS for Desktop 10.1. When I follow the tutorial for Collector called "Prepare your data in ArcGIS for Desktop" (http://doc.arcgis.com/en/collector/ios/create-maps/prepare-data-desktop.htm) and I get to the step to publish the data to our ArcGIS Online organization, the Feature Access parameters are "Create, Delete, Query, Update". The "Sync" parameter does not exist. Does the ability to allow users to work with feature service data offline exist only through ArcGIS 10.2?
