Open your Mission from the Missions page to see the participation counters that summarize its progress.
Four counters track participation: Claimed, Submitted, Verified and Declined. Claimed counts members who joined, Submitted counts completions awaiting your review, Verified counts confirmed participations, and Declined counts members who skipped the Mission.
The progress line compares verified participations with the required engagements. The Mission completes when the verified count reaches the required number.
Counters update as participants claim, submit, and are verified or reported, so refresh the page to see the latest state.
