I'm teaching at University of Trento. At the moment I'm using google meet + google classroom. Today my class was followed by 45 students, and everything worked well. Yesterday I was unable to record the lesson, but today it worked. As a backup, I used Audacity to record the audio (the slides are freely available online)
