When can I publish my course as ‘Show in Catalog’ or ‘Hide in Catalog’?
The "Show in Catalog" and "Hide in Catalog" options will be enabled only after all the 'Required Fields' are filled in on the 'Create Course page'.
Why am I not able to ‘Add Instance/Class of this Course’ for a Single-Instance Course on the Create Course Page?
The "Add Instance/Class of this Course" button is applicable only when creating a Multiple Instance/Class course.
How do I create a new course in the LMS?
Admin with the relevant privileges will be able to see the options to create a course: from the Toggle menu bar (Menu > Learning > Course) from the Quick widgets (Course > Create)
