After uninstalling the application for 3 months, I reinstalled it and found that the statuses of products in categories were not displayed.
They are only displayed for simple products and about 5% of variable products. 95% of variable products are not displayed. It does not matter whether the product is in stock or not, it does not matter when the product was uploaded, recently or a year ago. Everything is OK in the product details, the availability labels change after clicking on the variant.
