How can I fix the issue when the "Pre-Order" button is showing up for the wrong variant?

  • Open Themes section on the admin panel of your web store (Online Store → Themes);

  • Find Theme from the list which will be used with our installed app.

  • Click Actions → Edit Code.

  • Open the product.liquid template and add the code below to the beginning of the file:

<script>SPOCustom = {}; SPOCustom.customVariantSelectors = true;</script>

  • Save the template file.
