Your challenge participation count might look different depending where you look. There are a few reasons why this could happen.
In-App, we are showing the active participant count of a challenge. Meaning that anyone who's contributed at least one piece towards your challenge.
In Dashboard, we show active participants, but we also show stats of users who once participated in the challenge, uploaded their litter, and then unparticipated in your challenge.
In the report, we are showing all litters uploaded with a challenge. So if your Challenge is a Featured Challenge*, then any of the challenges connected to it will be counted. This means that you see participants from connected challenges, who might not actually be participating in your Featured Challenge, but merely in the connected challenge.
Please let us know if you have any questions regarding that at firstname.lastname@example.org
*Featured Challenges only available for upgraded Engage partner licenses.
