Hi @SoyMarketer a course can only be switched from Free to Paid once. If the course is switched from free to paid and back to free (or vice versa) after the course is published, the promotional announcements for the course will be permanently disabled. To have an overview of your account you can reach out to instructorsupport@udemy.com they will be able to provide you with further details.
