Participant/attendee able to speak to panelists during practice session?
We had a webinar today. The panelist was running late so I emailed the participants to let them know. When the panelist got into the practice session and we starting getting ready (I had not started the webinar yet) we heard a voice say "Is the webinar starting at 12:30?" I let them know if was supposed to start at 12:00. Was this a participant who was somehow able to speak to us in the practice session? Or someone with Zoom? It was so strange. I didn't think there was a way to communicate with participants before you officially start the webinar or vice versa.
