Hi Everybody,
I've already seen all the proposal and solutions proposed by the community about the topic in the question field but they don't work in my Jira plan. I don't know if I have some limitations due to Jira version but really I don't find a solution to this basic staff.
Just to explain better: I would like to define an automation that simply sum the effort of stories, tasks and sub-tasks into the epic field original estimates[days] as shown below.

Could someone give me some support?
Many thanks,
Paola
