When I have a hierarchy of Epic - Story - Subtask in Jira (which is the standard setting for a Scrum project in Jira), the planner’s swimlanes based on the parent field displays Epic-based swimlanes instead of Story-based swimlanes.
For a team with 120 subtasks for 8 Stories within 1-2 epics in a Sprint, this behaviour makes the move from Jira to Miro impossible.
Can you please make swimlanes based on the direct parent?
