I selected a Due date in the Task ticket field type and I cannot remove it. How can I remove or update the date?
Once a due date is set within the Task ticket field, you can remove or update the date by changing the ticket's Type.
Update the Type field to a Question, Problem, or Incident and submit the update. Then set the ticket Type back to Task and the due date is cleared.
