I have created custom product statuses, and have managed to figure out how to manually assign them in the product editor. However, when I upload a product file, all products in the upload file are switched to the default product status. I've tried a bunch of different ways of entering the status name in the spreadsheet, but they don't seem to work.
Even if I export a file of existing product, which shows the correct status, then just save it without making changes, it still doesn't work to import it.
Is there something I'm doing wrong, or is this a bug?
