ppwp-woocommerce-1.3.0 problem

Just an update, the issue was resolved with the customer via email.

As a reference for other users, by default, only when the order status is “completed” will customers receive the passwords/access links to access the protected content.

If you want to send passwords when orders are under processing, simply use the code snippet in this documentation:

Hope it helps.
