Printful: Print on Demand

Terrible experience. The app doesn't allow me to sync products without creating them from scratch in Printful. the integration functionality is shameful. I may need to switch to Printify. Let me clarify. This is for existing Printful Products I also have in Etsy. For newly created products I can add them fine. The issue is what do I do about the over 200 existing products not syncing.
