We've recently had issues with the fact that in an old authorisation email, the link still works to approve the timesheet, even when a new authorisation email has been issued. This has caused issues when:

o A timesheet approver has changed to a different person after the email was sent, but the first approver was still able to approve the timesheet.

o A candidate submitted a number of days before retracting and submitting a higher number, but the approval was actioned from the original email.
