One of my field crews has had an issue with a about 10 of his surveys failing to submit when he attempted to do so from the field. The surveys appeared to submit correctly (they disappear from his outbox) but they were missing from the hosted feature layer and related map so it is clear they did not. When we tried to edit and resubmit through the sent box we get the "Update error code 1019 - The specified feature could not be updated or does not exist." It would seem everything was filled out correctly and our survey does NOT use repeats. Has anyone else had any issue with this and if so is this a known bug? Also, the surveys are now stuck in his outbox. I've attached a log file from his device.
