Hi @JonOliveira589, I'm sorry you're having this problem. When you unpublish a course, it should take at least 48h for the change to reflect on the platform. If you have students who have already enrolled in your course, they will continue to have access when you unpublish the course (you can read more about this here). However, if it has been more than 48h and the course is still appearing for other students or if this is a new course that's under the review process, then this is certainly odd and I recommend reaching out to our team at instructorsupport@udemy.com with more details. They will be able to investigate this further.
