We have been using FieldMaps to edit a feature layer with a related table. When out in the field, we occasionally get this error when trying to add a new feature: "Unable to add related item. There was a problem with the layer's relationship. Please contact your administrator." This prevents any additional data from being collected.
We are working with an offline map and have collected dozens of features without issue. The error occurs randomly every few hours. Turning the tablet off and on usually makes the error go away, but not always. Does anyone know what could be causing this?
