We have added a tooltip with a warning message on the Download Orders From Shopify page: Order IDs should be fully numeric, like 5360204908230. For multiple Orders, use comma-separated values. This method for manually downloading Shopify Orders expects the long numeric Shopify Order ID, any other format will be rejected. This method is mostly used after initially integrating your Shopify site with Sellercloud or to re-download a problem order.
