Fixing breadcrumbs on a product page

[MilkyFloor]

I'm facing a problem: the breadcrumbs on the Magento 2 product page only show the current product, not the full path from the homepage through the categories. How can I set up the breadcrumbs to show the full path from the homepage to the product? What changes do I need to make to my code or configuration?

I also encountered the fact that breadcrumbs on the product page in Magento 2 show only the product, without categories. To fix this, first of all, checked that the product is linked to the main category, this is necessary for correct display. Also, studying amasty site helped me - I found useful solutions on it on how to set up full breadcrumbs. It is important to make changes to the layout and templates so that the system displays the path through the categories. Make sure that the setting for using categories in breadcrumbs is enabled, and if this does not help, you can install additional modules to improve navigation.
