You now have the option to use your debit card for your Reels. There are two ways you can add your debit card:
A. From your Profile > Account Details, then scroll down to Payment Information
B. When setting up a new Reel and choose your saving strategy. Once you're at the checkout, select Debit Card as the Payment Method. Add your debit card's information, then make sure to click Start Saving Now to activate your Reel.
Since debit transactions are faster to process you'll see them reflect on your Reel almost immediately. You can track them by going to My Reels, then selecting the active item you're saving for, and going to the Savings tab. Keep in mind that if there are any payment issues with your card your Reel will be automatically paused, and you'll get an email asking you to look into the status of your debit card before you can resume saving.
