Hi, I want to know why we can use custom attributes in email innvoice notification in draft orders.
It is very strange that through API we could create a Draft Order with custom attributes, they show in shopify admin webui, but we can't show them in email notification of the draft order.
We can use line item attributes, but ... why not draft order custom attributes?
I don't understant why. It is very strange.
Hope your answer, thanks.
