You can review your performance and the status of missions you previously participated in through your history:
Go to the "Missions" section: In the side menu (PC) or via the "Explore" button (App).
Select "History": At the top of the Missions page, you will see two buttons: "Missions" (active) and "History" (past). Click on "History".
Check your participation: Here you can see which missions you completed successfully and which ones expired.
Important Note: Only missions where you clicked the "Join/Participate" button will appear in your History. If a mission expired without you clicking to participate, it will not be recorded in your past activity list.
