Issues with screen sharing option. (4 months now)

hace 2 años

I've been having issues with the  screen sharing option for about 4 months now. My students too... So, basically they're unable to use it now and sometimes it happens to me too. If I want to share my screen twice on a lesson I have to refresh the website in order to be able to do it. Have you experienced this problem too or is it just me?
