The ArcGIS Survey123 field app corrupts selected choice list values when editing a record.
If a choice list includes code values with the format 001,002,..., ArcGIS Survey123 converts user selections to numbers (1,2,...) when editing a record from the inbox, causing data loss.
This issue is not reproducible in ArcGIS Survey123. If the issue occurs, contact Esri Support Services as additional information is required for further investigation.
