Has anyone seem this or got any solutions.
After upgrading from 2.4.2 to 2.4.3 the backend product page is missing the configurations (simple products associated to the configurable product) from configurable product page.
Is this a know issue or an upgrade issue?
Any help would be great.
This may be because the simple product is disabled or out-of-stock.
