As a Mission owner, your Mission moves through four states that control who can see and join it.
Active means the Mission is open in discovery and members can claim it. Paused means the Mission is temporarily stopped and hidden from discovery, and you can resume it at any time.
Completed means the verified participation count reached the required engagements. Cancelled means you ended the Mission, and unfilled slots were refunded.
Use the Pause, Resume and Cancel controls on your Mission page to move between these states.
