I'm using Shopify's Ebay connection to add my Shopify products to Ebay. Several products have loaded to Ebay successfully. The Shopify SKU was mapped to the Ebay Custom Label which works perfectly for me. Now, 1 day later, all of a sudden the Shopify SKU if not mapping to Custom Label correctly. Instead of the S.SKU, I'm getting a long number that means nothing to me. Any help would be appreciated.
