LearnDash Gift a course doesn’t send email

Hi everyone,

I have a client using LearnDash to sell courses via WooCommerce.
I recently installed the "LearnDash Gift a Course" plugin by HandsomeWP, and everything seems to be working well — the recipient receives a new user account with access to the course and an email with instructions on how to register on the website.

However, the gift message isn’t being delivered in the recipient’s email.
I’ve already enabled the "Gift Message" option in WooCommerce email settings and created a custom message, but it still doesn’t appear in the email.

Has anyone else experienced this issue or found a solution?
Any help would be greatly appreciated!
