I'm going crazy. I've read a lot of tutorials and marked "as solved" topics on override template on sales email. I'm trying to customize the sales_email_order_items, so I've created a file in [ModuleDir]/view/frontend/layout/sales_email_order_items.xml
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="items">
<block class="Magento\Sales\Block\Order\Email\Items" template="Vendor_Module::email/items.phtml"/>
</referenceBlock>
</body>
</page>
and created my custom template in [ModuleDir]/view/frontend/templates/email/items.phtml cleared cache and compiled, but nothing has changed.
Someone can help me?
