I tried to delete order history on Shein but it doesn’t allow me to modify the list, how can I delete or at least edit purchase history?

Order history is a record of all the purchases and transactions made by a customer on a specific online platform or store. It includes information such as the items purchased, the dates of purchase, order numbers, and payment information for each transaction.
Basically, it is not possible to remove your order history from Shein. Shein maintains a record of all orders made through their platform, and customers do not have the ability to delete this information. This practice is in line with their policy of preserving transaction records for administrative and customer support purposes.
However, you can archive your orders which will move them from the order list to the archived orders list enabling you to hide them if that’s the reason you want the list be altered. Keep in mind that you can access previously hidden orders and add them back to your primary order history by choosing the "Unarchive Order" option.
