I followed the steps you shared, but when I added the product categories for other languages and checked the links, they showed “No products available” for those languages, while products are available in the default (English) language.
I want you to check below list of category not translated please translate these from your end so I can add those in my menu for other languages, I no longer want steps, kindly do this for me as these are limited categories and I hope you will do this in couple of minutes.
