This issue can occur if you have other apps installed that override default variant behavior, such as Swatch King.
Common Conflict:
If Swatch King’s “Auto select variant” feature is enabled, it may interfere with how discounts are displayed—especially if your campaign relies on showing discounted prices for the default product rather than a selected variant.
Resolution:
To ensure your discount experience works correctly, please:
1. Go to Online Store > Themes > Customize.
2. Click on App embeds in the left sidebar.
3. Find the Swatch King app embed.
4. Disable the embed or toggle off the “Auto select variant” feature in the Swatch King settings panel.
Doing so will prevent automatic variant selection and allow our app to properly apply and display the discount.
