We randomly started seeing these errors on some of the products in a store. The screenshot is of the Admin/Products page, as seen after clicking the indicator which shows how many channels a product is published on. The affected products (which can no longer be added to cart in some markets) used to work fine in all markets, and at some point have stopped working in some but not all markets. Does anyone know why this error occurs? The fix appears to be to un-publish the product from all markets, and publish again. However this needs to be done for all affected products, and there’s no easy way to identify these errors; other than by opening the dropdown in the screenshot on all your products one by one. Any feedback appreciated.
NOTE: The product in the screenshot is set to continue selling when out of stock (hence the negative inventory count). The same errors are seen for various markets on other in-stock products.
