Hello, I am a safety incharge as well as a professor. I was guiding my students about [helmet safety](https://bestmotorcyclehelmets.net) through this platform because of COVID-19. Unfortunately, during class my video and audio freezes. I have to close the lecture and restart it to continue. I want to know what can be the reason? Thanks. ---
