Brother, I feel your pain.
I have been teaching EFL online for just over a year now, and it really takes some getting used to. I have spoken with over 3200 different students in the last year. Yes, three thousand two hundred different students.
I have used Zoom, and I thought it was truly horrible. There are many different platforms and software packages out there, but Zoom is, in my opinion, somewhere in the bottom third of what is available .
