After you redeem a reward from the Rewards tab, you can find the history of your rewards by going to My Orders. If you select your profile icon in the top right, My Orders will be at the bottom of the drop down menu.
On the My Orders tab you can view your Gift Cards, Swag*, and Custom Reward information.
If you don't receive your gift card, you are able to re-trigger the email to the email associated with your account. You will be able to check on the status of your swag order by finding your tracking information. For Custom Rewards, you will be able to see what rewards are pending and approved and by who.
PLEASE NOTE:
*if your swag order is from Axomo, it will not show up on My Orders. You can check on the status of your Axomo swag by following THIS article.
