Some of my AGOL users cannot sync photos that they have attached to points using Collector in offline mode. Attributes sync without problem. Attaching photos works when not in Offline mode. Sync does not throw an error.
Feature Layer is hosted in our organizational AGOL account.
Success in syncing attachments does not seem to be related to role (user or publisher).
Preferred attachment size is set to Large.
Collector version is 10.4.0
Any ideas? I have a number of internal staff and contractors performing field work which will be done without cell reception.
