I am new to Kanban, and I can't seem to figure out how to add an issue to my kanban board. I created a project, along with a testing board. However, I am unable to see the issues I created for the project on my kanban board, even after clearing all filters. When I go to the issue itself, and click "View on Board", it says "There are no boards which contain this issue.
How do you associate an issue with a board?
