Hello, thanks for the answer, but the calculation of coupons in the system is carried out correctly both in the cart and when processing orders in the admin-panel when applying the coupon to the order.
The whole system works perfectly!!!
In the previous version 3.9.8, the discount display for each product was displayed correctly and was calculated taking into account the discount for one product and for several products, and the display was correct, but in the new version 4.1.1 this calculation function in the order is not displayed correctly, since you have to manually calculate the cost of items at a discount for further processing of the order by the administrator.
Maybe there is a development of an additional “hook” or a plugin for administering orders to display the main price of the product and the discount price for each product (s)?
like for example here for the shopping cart: Display Regular & Sale Price @ Cart Table,
but so that this hook appears in the admin-order?
