Hello, I've been trying for a while to list the product with a "Generic" brand name and GTIN exemption, however keep getting the same error that GTIN exemption is required. I got the message when starting to recreate the listing with the approved category: "You have been granted an exemption to list without a product ID. This takes up to 1 hour to take effect. If you are unable to submit this right away, please save this listing as draft and retry after some time." Do exactly as it says and keep getting back to GTIN exemption is required. Please help. Feels like I missing something, but can't see what.
