Our team is building one product to support online learners, so can you guys take us through your problems when it comes to self-learning or online learning? In case these 4 problems are not really your pain, please tell us more about your problem-solving solutions? We believe self-learning is the future of education, so it would be great if we can share some ideas and problems, solutions for this topic. Thanks for your help, and I apologize if it is not suitable for the subreddit.
