We are using Retail Barcode Labels to create barcodes for our products for tagging. Currently, we have our google and Facebook channel connected and the errors stemming from our product listings are "Invalid barcode". The items have barcodes that were generated from the app, why are they showing as invalid? We also used barcodelookup.com to see, and once again the barcodes are invalid. How can we get around this? (reached out to the support of the app, but haven't heard back yet). Anyone else facing this issue?
