Problem:
I have been using the WPML editor to translate products from English to Vietnamese. I utilize the "upsell" field in WooCommerce product data to showcase related products on the frontend. However, I am unable to edit this field for the Vietnamese language.
Solution:
You should not edit translated products directly from the Product editor, as these fields are synchronized with the default language's fields and remain locked. Instead, ensure that the products you set as "upsell" are also translated into Vietnamese. When you add upsell products to the main product and complete the main product's translation, the translated versions of the upsell products will automatically link with the translated main product. Thus, the key is to ensure that all upsell products have their respective Vietnamese translations.
