I was just a Participant in a Collaborate session. On my IPad, I used the Student App to join the session. When the session started I was talking to someone in my office so I tried to mute the sound, physically using the volume button on the IPad. I was not able to completely mute the sound: it went down to level 1, but it wouldn't completely Mute. Was the app preventing me Mute the sound?
Thanks for any advice.
