Andrew Stauffer,
The syncing problem doesn't seem to be an issue any more. I think it's must have been addressed in the latest release of updates for ArcGIS online.
However, now I have another issue... All of the layers that I have available for download from open data come from a single map service that is published to our ArcGIS server. And all of them, but one, seem to download just fine. The problem layer is the "Omaha Zoning" layer. I cannot figure out why it won't download.
Here is the link to my open data site: http://data.dogis.opendata.arcgis.com
Would appreciate any help. Thanks. Nataliya
