Hi,
I was able to login to the FTP with that change. Thanks.
I also did further tests and as a customer I can confirm I'm receiving the email WITH the PDF invoice file attached.
Regarding the copy sent to the email address you specified in the plugin setting, it is taken into account.
I thought there might be a bug because the email address didn't appear in the "BCC" of the email in the Email history, but that's just because the email is stored in the email history before the PDF invoice plugin adds the BCC. So it's still taken into account.
I've moved the email address to the "BCC" field of the "order status notification" email in the menu System>Emails and now the email address appears in the BCC field of the email history:

However, I tried with one of my email addresses and I didn't receive it. This means that there must be a problem with your hosting email server discarding the BCC field, probably to avoid spam.
Thus, I would recommend to contact your hosting support with a copy of an email from the email history with the BCC setting filled and ask them why the email was not received by the email address in the BCC field even though it was received by the email address in the "to".
However, I'm afraid that the only solution to make this work would be to configure your Joomla configuration email settings to go through a paid email service provider like Elastic Email.
Best regards,
Nicolas
