As the Challenge Host, you'll make the final determination regarding the awarding of prizes. We can set your Challenge up so that when the Challenge ends, winners will not be notified in the app until you give the approval to do so. We'll be in touch with you and once you give us the go ahead, we'll notify the winner(s).
