ArcGIS Server 10.3, ipad Air (iOS)
I have a service to which I can successfully add a new feature while disconnected. Then, with connectivity restored, I sync. The sync appears successful. But the new feature is not written to the database. A json query of the rest endpoint for its ID returns "no results," and the geometry is not present in the feature class.
Adding a feature to the same service while connected is successful. So it appears to be related to the sync.
How can I troubleshoot this?
