I wrongly added a subtask to a parent issue. How do I remove the subtask?
I would really like to delete the subtask entirely but probably don't have permission (impossible to tell for sure with this UI since menus that I can't use just don't show so I'm left wondering if I'm looking in right place but don't have permission or looking in wrong place).
But even if I can't delete the subtask, I should be able to remove it from association with its parent task. There is a "+" button near the Subtasks label in the parent issue, but no corresponding "-". Nor can I find any other way to remove the association.
