Why isn't my discount code working?

I'm experiencing frustration with a discount code that seems to be malfunctioning in my online store. I've carefully created the code, but when customers try to apply it during checkout, it's either not being recognized or generating an error message. This is causing potential lost sales and customer confusion. I need to understand the common reasons why discount codes fail and how to troubleshoot and resolve these issues quickly and effectively.

TL;DR - Quick Answer

Discount popup display problems - wrong position, not appearing, or appearing twice - typically stem from CSS z-index conflicts with other apps, theme CSS overrides, or multiple Growth Suite campaigns targeting the same page.

Fixing Discount Popup Display Problems

Popup display issues are almost always CSS or JavaScript conflicts with other apps or your theme. Growth Suite's High-Fidelity Countdown Timer and popup components use fixed positioning with high z-index values, but competing apps can interfere.
