Why can't shoppers see the hidden gifts in my Find & Earn event?

Check these in order:

1. The event has Live ticked and today falls between its Start Date and End Date. Only live events within their dates show gifts.
2. The event has gifts. Open it, go to Gifts, and add at least one.
3. Each gift's Placement matches where you're looking. If you filled in Page slug, the gift only appears on that one product or category page.

Also create the coupon codes you used in Marketing → Coupons, so winners can actually redeem them.
