I was testing adding an Epic in the Roadmap, set an end date, then added a child story, enabled due date in stories, set a due date that was after the Epic end date, but the Epic date in the graph didn't change. Shouldn't it change or at least have some warning?

Note, there is a warning in the UI (probably added since this issue was first created):

Side note: in the above screenshot I have the new Schedule child issues by dates setting enabled.

Does anyone know if this is something that might be developed in the near future? Or if there are any workarounds? 

Any automation for that while waiting for the feature, please ? 

Total must have for tool of this size and usage.

Absolutely! I am gobsmacked that the Due Date doesnt automatically calculate based on Start Date and Original Estimate.  I cant use this until this is done so it is back to Excel unfortunately!!!

This should literally be a feature already, of course epics should adjust to the date of the tasks, stories and bugs that are associated with them

This feature should be basic! It's so obvious! 

without this feature Excel is a better tool

This is a much much needed feature.. GitLab has a similar solution for some time now. Why is this still under consideration, i don't understand why you would consider to include or not include this feature?

+1 to this. Surprised this isn't how it already behaves...
