Hi there
When I updated to your excellent theme I have found a plugin that works OK with Kadence, Porto and Storefront does not function correctly with Xstore
In the link below when you select an optionyou should see a qty against each this is missing when Xstore is the theme. Change to any other and the qty appear.
The plugin suggested trying below as a code snippet but this hasn’t fixed it and wondered maybe you had a solution.
add_filter( ‘woocommerce_product_variation_title_include_attributes’, ‘__return_true’, 99 );
