I'm trying to build a class in CoursePress Pro using Chat integration. I added the "Live Chat" element in the unit building area. However, I could not see the chat area when logged in as myself. But, when I logged out, I saw it. It prompted me to login to the chat area with a username and email. I did, with my personal email address. Then, when I tried to log in as myself-the-course-administrator (using my work email), it told me "Email already registered." If the point of the chat in the course is for registered users to chat, I feel confused by being disallowed from joining chat due to using an email associated with my course log-in. Can you help?
