We have added custom start and end dates to our Jira project and kanban board and are able to add the fields to AR dashboard display. However, when we try to use these new dates when configuring the Scheduling screen, AR won't let us choose them from the drop down in which they are displayed. Instead, it gives this warning: "Make sure to add this date field to all the issue sources of this plan."
What else do we have to do to use these dates?
