WBS GAntt - unable to set WBS start and end date link with Jira start and end date

[Surbhi Shah]

I am on trial month of WBS Gantt.   I want Jira Start & End Dates to get reflect on WBS GANTT.  So that any update done on Gantt gets directly update in story/task and vice versa.

WBS -> Fields is not editable for me
