We have folks in the field using collector. The map and the feature service has been used before with no problems. Yesterday we had fields deleting themselves as the form was being populated. So once the user got through most of the drop downs the data above would be deleted. The work around was to publish the same feature service into a new map. I should point out that this is not the first time this has happened. I meant to post something sooner but I almost never use the forums since they switched to geonet. Has anyone had this issue before? I originally thought that the feature service was the problem even though I have not altered it in any way since it was working....but using the same feature service in a different map works...makes no sense.
