Show how to turn on the sound.
For a while, I thought I was the dumbo BUT … 2 people I have recommended ROM coach to, told me they’ve stopped using it since the sound sometimes does not turn on.
I had to talk to your support to find out you have to turn on the ringer sound in order to hear Eric. Most people turn that off when they want to concentrate on something else. And not everyone knows it affects the video sound.
Maybe have something pop up when the sound is off “For sound, turn on ringer sound”?
