I am attempting to use Jira Portfolio for managing our larger initiatives but can not get Epics or Initiatives start dates to work. Scheduled Start date looks locked down and Target Date, which is set to Jan 2020 for the second Initiative isn't being recognized. I changed the view to be by Target Date and that didn't work. I also changed the earliest start date to Jan 2020 and no dice. The Initiative doesn't have anything open beneath it other than an Epic and all are set to "backlog" status.
Any advice on how to get this to work?
