I am the administrator and host for my account. I have enabled chat, enabled private chat, and made sure that everyone can chat with everyone else in the meeting settings. However, the actual chat function doesn't show up during my meetings - the chat icon isn't in my meeting controls. How do I get the chat icon to show up in my meeting controls for both me and my participants? We want to chat during meetings but have no ability to do so. I've been trying to get this to work for an hour, so any help you can give would be great. If it matters, I have a paid account.
