I am trying to make my email templates work.
I have the following scenario:
I have a custom theme that does not influence the standard mail templates. The problem persists, even when I am activating the Magento Luma theme.
The Problem:
No Products are showing up inside the order confirmation mail.
To display products, inside the mail, following snipped is needed:
{{layout handle="sales_email_order_items" order_id=$order_id area="frontend"}}
My Magento version is 2.4.3; I upgraded from version 2.4.1 where the problem was the same. So updating didn't help.
