before this commit,
the wording of the visibility options can be quite confusing.
after this commit,
- Visibility has been updated
- Visible to all: I see those training to the public
- Visible to logged users only: I am a B2B business, and I do not want the
public to see what I offer + the pricing I have on those
- Visible to members only: I am a school, I want to invite my students but
external visitors should not be able to enroll
- Move the field above the "enroll policy"
- Enroll Policy has been set to invite when visibility is set as a Course
attendee and hide the enroll policy
