Up-Sell & Cross-Sell in product page are not working anymore for some unknown reason. I can’t add new products there, because it won’t find any products even tho there is multiple products in my product catalog.
Is this an Basel or woocommerce issue?
To better assist you, could you kindly test the functionality with default WordPress themes such as TwentyTwenty or WooCommerce Storefront? This will help us determine whether the issue stems from our theme or elsewhere.
