So I was using the Collector app and I downloaded my map onto my device to work with it while I was offline. As I was working with it, I made some edits and added in some attribute information. Once that was completed, it said I had some features that needed to be synced so I would start the synchronization process. Every time I have attempted this, an error message pops up and says Sync Error An error has occurred while synchronizing edits. So I select the 'more' option on the error message and it says operation rolled back. I don't know why it would be doing this and i'm not sure if anyone else has encountered this issue. If anyone knows what could be happening your help would be greatly appreciated!
