Good day to all!
I have a problem. I am creating a "Test Category" – A parent category. Then I create a "Test Subcategory" – A Subcategory to the Parent category. When updating the page, the parent category does not assign a subcategory. BUT! In the category, settings-everything is specified correctly and remains the same. When adding a product, it is considered as a subcategory of is.
The discomfort is that the parent category with products and their quantity is not displayed on the Store page. But if you go to the Parent category, the subcategory will be located with products.
