I am using PayPal Express Checkout on my Magento 2 site. The payment confirmation emails contain a description (configurable product name only), quantity, and amount. At a minimum, I would like these emails to also contain the other attributes such as size, etc, or possibly the sku since those attributes are contained in my skus. Is there a way to get these attributes into the PayPal payment confirmation email? This would be more convenient for us than using the pdf invoice for order picking.
I found a hint on how to do this in an old answer to another question that probably applies to Magento 1. Not sure how applicable it is to the current code.
