Hi @АленаАрьянова sorry to hear that you're having problems uploading your lectures. If a draft course doesn't have a price added yet, video lectures longer than 2 hrs will appear as "unpublished". This behaviour is expected for free courses. If this is not intended to be a free course, you can add a price to your course to continue adding content. Here is an article on how to add a price to your course.
If you need any further assistance with this, please don't hesitate to contact email@example.com - our team will be happy to help!
