We are moving all issues from our company-managed project to our team-managed project. Some of these issues are linked to Sprints. You can see the Sprint in the migrated issue from company-managed project to team-managed project. But it does not appear on our Sprint Board.
Then, we created the sprints in our team-managed project and tried linking the issue to the new Sprint. It seems we can link the issue to the new Sprint but when we go to the backlog to Start the Sprint, no issue appears linked to the Sprint.
How do we re-establish the link in the team-managed project?
