We have added Moodle 2019 courses in bulk.
By default, 2019 courses are "NOT VISIBLE", so they are NOT displayed to students as it is. When you are ready to display the course to students, you need to change the "Visible" setting to "Show" on the Edit course settings page in Administration block.
2018 courses are now turned to be "NOT VISIBLE" to students.
If you have any questions and concerns, please contact us.
