I've worked very well with Webex in the last semester. I was able to take part in events and also hold my own meetings. For 3 weeks now I have been regularly "flying" out of Webex meetings when the lecturers divide us into group rooms. The problem is on my home laptop. It's not because of the WiFi, I also reinstalled the app several times. I work with Wndows 10. Hopefully you can help me as the events on the mobile phone display are not very profitable.
