If you find that your Q&A Session within a meeting does not work, you might need to switch to chat instead, following the steps below.
As a workaround, you can enable Instant Messenger to work instead.
1. Restart IM by clicking on the Presentation icon (looks like a monitor – see below) to “Manage Presentable Content.”
2. A “Presentable Content” window will open and you will want to click on the Q&A “Stop Presenting” choice.
3. Then “Close” and you will get a pop up message that you should click to “Turn on Meeting IM”.
