One participant is able to join meeting by audio but her image is not appearing and she is not seeing others. When she is connecting to GoToMeetings her pictures is visible on the screen that says 'here's how you will appear when you join' but when she then clicks 'OK I'm ready' and is taken to the meeting screen all she sees is a box with her initials - and the camera icon is greyed out.
(NB under the oraniser settings the option 'attendees can share webcams' is ticked)
