I am trialling WBS Gantt chart for JIRA Cloud.
In that chart, I see a duration field. I would have assumed that it would pull this field from the "Original Estimate" in JIRA - but that does not seem to be the case.
Where is this value stored in the individual JIRA issue? I would like my developers to update estimates directly in the JIRA issue so they don't have to suffer the pain of looking at Gantt charts.
