I have a fairly straightforward Approval Request workflow that sends me an approval request notification after a customer completes a form. Whenever I click the Open Request button from the email notification and click Approve, I see an error message that the link has already been used. When I check the sheet associated with this form, the column set up for displaying the Submitted/Approved/Declined status shows Declined. I have the Modified Time and Modified By columns active, and it seems to show that automation@smartsheet.com is making this change, even though the only auto-decline workflow I have is when the customer selects an embargoed or comprehensively sanctioned country (e.g., North Korea). There are no other auto-decline workflows that don't require me to manually select Decline.
There was a similar question asked here a couple of years ago, and an answer or solution was never posted. I would appreciate any help or guidance that can be offered.
