Attachment does not send

Hello.

I have properly installed your plugin and configured all emails. Everything looks nice in the live preview, when I send a test email, all emails look good in the browser (Gmail, Outlook web), Outlook mobile and Outlook desktop. Along with the test mail, the attachment also goes where I set it to go.

Problems arise when a customer places an order and WooCommerce automatically initiates sending an email:
1. The attachment does not arrive in the e-mail to the customer
2. The columns are broken in the Outlook desktop version (mail to customer and administrator), while in the browser (Gmail, Outlook web) and Outlook mobile it looks normal.

– Outlook MS365 is latest (2404)
– the email template that should send the attachment and that is sent to the customer is “Order on-hold”

Can you help me?
Best regards.
