Hi @davidgreentec
I’m not familiar with Spanish, so I tried translating your message to English using Google translate. I see that your problems are two-fold:
1. Order notification emails for admins are not working after WordPress 5.0.3 + WooCommerce 3.5.4 update.
2. You don’t see the billing address in the delivery notes (in your PDF invoices).
Regarding order notification emails, I would recommend that you test this out first by using an Email Log plugin in your site. Once you have installed it, try placing a test order and see if the mail gets recorded in the log. If it does, this problem might be related to your server. WooCommerce uses the built-in email system in WordPress to send emails (the PHP mail() function). In many cases, your web host might be filtering these emails resulting in these problems.
Another reason that we have seen with host-related email troubles is incorrectly-configured SPF (Sender Policy Framework) and DKIM (DomainKey Identification Method) records. Essentially, these are records set by your host in order to identify your domain, when emails are being sent. If these records are not configured correctly by your host, this may lead to email issues. Please check this article for more info on SPF and DKIM configurations: https://blog.endpoint.com/2014/04/spf-dkim-and-dmarc-brief-explanation.html
Anyway, reach out to your web host’s settings, and have them look into your email system to see if there’s something blocking this. You can read more on email-related troubles and on fixing them here: https://docs.woocommerce.com/document/email-faq/
Regarding the second problem with the billing address – I believe you are using a third party plugin to show up the PDF invoices. If this is not working as expected, I recommend that you reach out to their support folks, and ask them to look into this for you. They should be able to come up with a solution for this.
