Trying to build a Plan for all Issues assigned to a particular set of individuals, so we can see a holistic view of the work.
Have built a JQL Filter along the lines of:
Assignee = X OR Reporter = X OR Epic = Y OR ParentEpic = Y
This returns all the relevant issues.
However in the Plan, a Subtask sometimes does not display if it has Parents missing from the above Filter output.
Essentially want to see the hierarchy of Issues wherever any single Issue in the hierarchy is Assigned to X, else show nothing.
