Failed to join the meeting in Cape Town virtually

IFLA Journal Editorial Committee meeting was held in Cape Town yesterday at 2:00 p.m. (Cape Town) (Beijing Time: 8:00 p.m.). An IFLA HQ officer asked me to join the meeting via Skype. I returned to my office, opened Skype earlier, and got the message from the officer. However, there was no further response, and I was not able to join the meeting finally. I think there was perhaps a technical problem that they cannot solve, or they are too busy for the meeting to solve the problem. Sadly, I kept online for about two hours and got no message from them.
