A customer is saying their automatically applied discount disappeared. What could cause that?
I'm experiencing a frustrating situation where a discount code that was supposed to be automatically applied to my cart suddenly vanished. This happened midway through my checkout process, and now I'm confused about why the discount disappeared. I've spent time selecting products, added them to my cart, and was expecting the discount to remain, but now it's gone. What technical or system-related reasons could explain this sudden discount removal? I need to understand the potential causes to prevent this from happening again and ensure a smooth customer experience in my e-commerce store.
