unable to sync on an iphone, but only for one user in particular.
1. Close the app - restart the app and try again.
2. Change to send only and try again with sync. Take a look in the webbrowser if the Changes have been received. Remove the maps and download again.
3. Move the files in Itunes and use a python-command in Arcmap to retrieve the data from the runtime-database.
We encountered this error last week, and changing the settings to Push only allowed the data to sync correctly. We then deleted and reloaded the map and everything is working again.
You are a champion, Johan!
