It seems that private promotion coupons aren't working on our site as I expected based on the documentation
A private coupon is a discount code that is assigned to a single customer.
My understanding is that I am supposed to be able to generate a specific number of codes that start and end with a prefix and suffix I set, and give each one of the codes to one specific customer, and the code will then be tied to their account. However, the private codes I created appear to work just like a normal public code and give anyone who uses them the discount if the same code is input by multiple users.
Has anyone run into this?
