For each individual GooseChase mission, organizers can set whether submissions are shown or hidden to participants in the activity feed by following these steps:
Create a new mission or edit an existing mission from the “Missions” page of your game.
Towards the bottom of the mission form, expand the “Advanced Settings” button.
Edit the “Shown in Feed” dropdown depending on whether you’d like the submission to be shown or hidden to other players.
Save your mission.
By default, Text and GPS Missions are set to “Hidden in Feed” when created, while Photo/Video missions are set to “Shown in Feed”.
