If you're creating content as part of @Binance Square Official 's Creatorpad, this concerns you:

Campaign winners will be notified via a push notification under Creator Center > Square Assistant and will receive rewards in the form of vouchers, which will be distributed within 21 working days after the activity ends.

The most important thing is that the voucher will only be available for 7 days, so you have a 7-day window to claim it, or you'll lose the rewards. So, always check Square assistant notifications and after an activity ends, keep an eye on the rewards center, at least once a week, or check it every day.
