Hi!
My goal is to restrict the ability to edit fields on closed tickets to only a group of Administrators.
I already managed to restrict almost every field on a ticket (epic link, story points, reporter, etc) using the property key jira.permission.edit.group.1=administrators, but for some reason, assignee is still able to be edited by non-admin users after the ticket has been closed.
How can I go about preventing this field from being edited post-close (except by admins)?
