I want to do cross project sprint planning. I have two next gen projects which contain epics, and those epics contain issues.
I created a third classic project and am attempting to create kanban board which shows all issues from the next gen projects.
I have mapped all statuses to columns. I created a filter which selects all tasks from both next gen projects and I created the board using this filter.
The problem is that the board only shows my epics and issues which are not assigned to an epic. As soon as I assign an issue to an epic, it disappears from the board.
