Currently, when a course expires, users can't easily track or view their previous purchases, making it challenging for them to renew. To renew an expired course, they must navigate back to the homepage and purchase it again, which may cause some users to lose track—even if they’re interested in renewing. Additionally, we'd like to offer a discount to encourage users to renew, helping us retain existing customers. However, the current model doesn’t support this feature, which is essential for improving user experience and retention.
