Good morning, my school has hundreds of Samsung Flip 4 Pro WM85B, practically in every classroom in the school. I have a problem which I am trying to summarise. I need to do lessons in DAD for a pupil (health problems), and at the same time in the class. The best thing would be to do the lesson on the blackboard and the pupil at home to see on the PC what is being done on the blackboard, BUT I CANNOT? Greetings
