Hello everyone, I am a new instructor. I am currently in a bit of trouble and need help. When I was uploading my course, I couldn't upload the course syllabus. I don't know why. I have filled in all the titles. The videos have also been uploaded. After checking, there seems to be no problem with the content. Everything looks fine. However, the course syllabus always shows that it is not working properly. I can't submit it. As a result, the entire course can't be published. Please help. Thank you.
