So I figured out how to solve the issue I was having; although not 100% sure what caused it. I had custom e-mail templates from my theme in my woocommerce e-mail settings. Disabling them solved my issue. Now I am unsure if it is an issue with woocommerce in general or just with the Post SMTP plugin, but perhaps it will help others along if they see the same issue.

Thank you for a fast reply. I included my diag results just in case. I apologize for the thrash.

I am seeing the same issue where new orders are not sending an e-mail but other e-mail types are going through (via the log). I can manually push the new order e-mails through but they are not happening automatically.

E-mail validation is disabled.

POST SMTP 1.7.7

Any thoughts on where to look would be great.

This issue is with the check to verify if the admin notice is flagged to be shown. You can successfully comment it out to access your site. You will have to be able to access the wordpress back content to edit the file.

Starting at line 27 in the file:
/wp-content/themes/butterfly-adobe/function.php

if( !function_exists( 'the_field' ) && empty( get_option( 'butterfly-abode-notice-dismissed' ) ) ) {
add_action('wp_ajax_butterfly_abode_dismiss_notice', array( $this, 'hide_notice' ));
	add_action( 'admin_notices', array( $this, 'admin_notice' ) );
}
