I cannot make "start date" and "end date" of issues under epics visible on roadmap...
With the default setting, Issue does not have "start date" and "end date" properties, but I can add them by changing the default settings.
Once I have added those properties, however, those are still invisible on roadmap...
Is it impossible? Or only possible with premium roadmap???
The image below from https://www.atlassian.com/ja/software/jira/features/roadmaps?tab=basic shows that stories under epics' "start date" and "end date" are visible on roadmap...
