A "Completed-Flagged" result in a document verification report indicates that, depending on the potential reasons for the flag, you may need to manually review the case and make an informed decision. You could investigate the reason for the flag, such as an image mismatch—potentially caused by factors like poor ID image quality or glare—or an issue with the liveness check. Assessing these factors can help you manually determine whether the issue can be disregarded or requires further action.
