I have been using FieldMaps and after I submit a new feature, it appears. When I return from the field and view the synced data, only some of my collected features appear, and when I refer back to the FieldMaps app the data is missing there as well. I have had this happen a few times but it is sporadic. Some features will remain, but others will disappear entirely as if they were not collected. My configuration is set up for offline. Any ideas as to what's going on or how to prevent it in the future?
