Garbage... Now I remember why I deleted this app a while ago. Got an uber gift card from someone, and now I need to use it. I have searched high and low in the wallet section of the app, and guess what. Nowhere does it say, redeem a gift card. Smh. Figured it out! For those of you following all the tips/links on google and still failing, add the gift card number to the promo code section, and make sure there's no space at the end. Then wait a few minutes and it will appear. GOOD LUCK!
