For more than once I tried to redeem a promo code in the app and it not work. After the first try the code is not usable anymore. This time I try to complain and it state the voucher is not applicable to my region, although all the conditions stated in the email are met. I mean, I am in the right country were the voucher apply, I passed the minimum amount by 5 euros excluding delivery, and it was 5 days before the end of the voucher. Looks like Uber eats is fishing for purchases.
