I will explain my case in steps to make things more clear:
I have a Tutor LMS page with people already enrolled in a course that is public
I want to make this course private (the one that is public and has people already enrolled)
When I do that they don’t see the course any more
Do I have to enroll everyone again if I set the existing course with enrolled students to private? Maybe this is a free Tutor LMS problem and If I will buy the Pro version they will stay enrolled and I don’t have to do anything manually?
