Why does Wcart ask for a reason when I cancel an order?

When you change an order to Cancelled and it wasn't cancelled before, a second dropdown appears so you can record why:

• Customer changed/cancelled order
• Fraudulent order
• Items unavailable
• Payment declined
• Other

Pick one and click Update Status. The reason is saved on the order and added to the Timeline, for example "Status changed from Pending to Cancelled — reason: customer". It also feeds your cancellation reports. Choosing Fraudulent order also records the order's fraud decision as cancelled.

If you don't change the default, Customer changed/cancelled order is saved.
