My organization has SharePoint 2013 on-premise and utilizing Nintex Workflow 2013. My user is having issue with the workflow outcome still showing Pending even when the task is approved. When viewing the workflow history, i can see that the Status is In Progress and Outcome is Pending but when i click on the Title (Third Level Approval) and view the approval task, it shows that it has been approved (screenshots below). So now the workflow is not proceeding forward and is stuck on this step.
Only possible cause I can think of for this behavior is if user clicked on the Save button multiple times during approving, but I am not sure. Any thoughts on the issue?
