Super stupid question which I cannot again get to play nice.
Basically have an 'issue' and several subtasks to it. The issue and subtask share a workflow. I have a set of fields that are on the Subtask (say 15 across 5 subtasks) which I also have on the main 'issue' ticket. I want to basically source the fields from the 'child' subtasks to the parent 'issue' ticket when subtask are either updated or transitioned. Managed to get it via Custom JWT text field but can't do via a either Read / Write on linked issues / subtasks (I do identify a mapping of child to parent; but then I don't manage to intersect the issue selector seemingly)
the options - filtering by issue link type; write on subtasks (parent to child I assume); write on sibling taks (subtask to subtask) don't seem to help. Could you suggest an approach
