Shopify POD quantities and Amazon

Strange how quirks keep popping up!  I have been putting my POD products on Amazon.  My SPOD products go in seamlessly!  However, my Printify products are being rejected by Amazon.  Why?  Well, Printify doesn't pass on quantity to Shopify, so the quantity is 0 when it goes into Amazon, and is rejected.


If the product is a single product, like a tote, I can update the quantity from 0 in the Amazon interface..  If the product has variants like color or size, well, the variants do not go in as a single product, and even if I update the quantity to each variant, it still isn't combined into a single product.


Anyone else importing to Amazon using Printify?
