Some of my Collector Users are getting an error while trying to sync their offline edits.
The error message is as follows:
"An Error Occurred While Synchronizing Edits" - Service: [Rest URL] "Unable to synchronize replica, importing delta data changes failed" OR "Operation Rollback"
Some users are able to sync their data while others aren't (using the same feature service).
Did you ever find a solution to this? We are running into the same issue. Both users were able to sync all morning and now one user is not able to sync and is getting the same error.
First try syncing over wifi. If that doesn't work you will have to manually take the data off of the device.
