Hello,
I see a lot of question about this topics (please make it clearer in jira itself!) but the fact that the status of the issue and the status of an epic is not linked is very perturbing.
So I try to change our workflow to update the custom field 'epic status' but there is no "custom field update" possibility. And I don"t want to pay for a plugin or to add a script that will be probably outdate to each jira release. So How can I make something that work that help me to work with epic, and when I mark the issue as done, the fu**ng field "epic status' is updated too
