We have a pop up published on our site which gives the person signing up a $20 discount off their order. After entering their email address they are given a unique code.
When getting to checkout, there is a discount code preloaded into the discount code section, that isn’t the discount code that was given to the customer - the code that is in there is a totally separate code that was not created through Klaviyo, was made in Shopify. The code appearing is completely unrelated to Klaviyo or this promo, it just happens to be the same $ amount.
We do not have a fallback coupon set up for this pop up.
Any ideas on how/why this is happening?
