I have uploaded all of my users through the CSV import with a status of 2.
I've reviewed the courses and the students are enrolled and none of them have a status of Course Under Evaluation.
When a student logins in for the first time, then goes to My Courses all of the course statuses have changed to Course Under Evaluation.
How can I stop this from happening?
Here is a video showing what happens https://vimeo.com/194044852/1a4f78b2a5
Please try syncing the courses from wp-admin->lms->functions->course students.
If the issue still persists then please share the import file with us which you used, to check it.
