I've tried editing everything that has to do with Shipping, but I can't figure out what causes this warning:
Old discount tag ApplyShippingDiscount cannot be used with new discount. Use ShippingDiscountProfileID and/or InternationalShippingDiscountProfileID as required under ShippingDetails.
It doesn't prevent me from listing, but it's been showing up every time for the past couple of weeks.....
Any help would be appreciated.
