How does gift swapping work?
Gift swapping allows you to replace your gift with another one. To see what options are available, tap the Swap gift button.
Unless otherwise noted, you can choose any of the options that pop up for your gift. Once you've selected a gift you want, you can select it and tap Swap gift. Then you'll be able to select any options (if applicable) and enter your address to accept the gift.
Or, if you want to keep your original gift, you can just tap out of the Swap Gift window.
Since we need to bill your gift sender the correct amount based on the gift selected, they'll be able to see the gift that you swapped to, but hey, it's 2020, right?
