I am a teacher, I must run online courses at home because COVID-19. Although I chose the highest plan-Internet 600, its actual upload speed is only 20M. When I shared my screen with more than 15 students. the upload bandwidth is fully occupied, there will be a significant delay in the entire process. This led to a serious decrease in the quality of my courses

I know everyone is very difficult currently. Please for student’s education, upgrade the teacher's upload speed to 200M for free if possible.
