I'm not using Advanced Roadmaps, just a normal Jira software project.
I have 2 boards that I now want to combine into one. I've managed to get everything into the new board with a filter except the sprints don't show on the timeline view. They are in the backlog and active sprints view fine but because I didn't create the sprints from this board, the sprint row at the top of the timeline is empty. Is it possible to fix this?
