Problem:
You are unable to translate the 'related product' field manually or automatically in WPML.
Solution:
The 'linked products' field is locked for product translations and cannot be translated directly as it syncs with the original product. Here's how to manage it:
1. Create some products and translate them.
2. Add some of these products to the 'linked products' field.
3. Translate the product to which you added items in the 'linked products' field.
4. Ensure that the products in the 'linked products' field are translated first. They will then appear correctly in the translated product.
