Why can't students see the coupon after it's been applied to a specific product?

中文 To provide users with a better experience, the system has set multiple constraint rules for displaying coupon content. For example, if a merchant configures products for a coupon in the background, but learners cannot see them, the following situations may occur: 1. The selected products do not meet the usage threshold of the coupon. Example: A merchant's coupon offers a 2 - yuan discount when the purchase reaches 10 yuan. If the merchant selects a 9 - yuan图文课程, it does not meet the usage threshold of the coupon, and the product will not be displayed on the learner's end. PS: Multiple knowledge products cannot be purchased at once, while multiple physical products can. 2. The merchant has selected a course that is participating in a marketing event, and the coupon usage condition is set to be available only when purchasing products at the original price. Example: The merchant sets the coupon to be available only when purchasing products at the original price, but selects products participating in time - limited discounts and flash sales. In this case, the products will not be displayed on the learner's end. 3. There is a conflict between the super - member benefits and the coupon conditions. Example: The merchant sets the condition that super - member discounted products cannot be used in combination with coupons. If the coupon selects relevant products, the relevant products will not be displayed when super - members enter the coupon collection page. The above rules also apply to custom - recommended products. Recommended products may also not be displayed on the learner's end due to the above situations.
