I have been working with a team of ecologists who are collecting data on their iphones using Collector for Arcgis. Unfortunately, they are unable to sync it. They have tried collecting and syncing from different devices (iphone and ipads) and they keep getting an error (see error image attached).
They were able to sync their data on the first day of fieldwork but not afterwards.
A bit of extra information:
Any idea of what could be the problem?
Thanks in advances for your help.
I'm having this same problem and am guessing it is the photos. I don't understand why there is no option for selective sync. The photo resolution cannot be changed on the iPad so after 1 day of data collection we may have 1 Gb of photos, quite a bit to sync. If only syncing of photos could be turned off and done later in the office...
...allthough looking now at your error, that is not the attachment error. That error is related to the collector app not being able to contact the server. Do you have background refresh turned on or off for collector?
