We have a way to easily remove discounts off an open order from the POS app. Below is a detailed guide on how to remove discounts:
1. On an open order, tap on the "upside arrow" icon in the bottom right corner to expand the order.
2. Once the order has been expanded, you will see "Discount" line there. Just click the "X" to remove the discount.
3. You will receive this pop-up message; select "Yes" option
4. The "Discount" should reflect $0.00 after you click "yes" on the pop-up.
5. Now, you can complete the payment.
