The “C” and the “Anmelden” Button is shown
can you post a screenshot of that screen? I am not quite sure what you are talking about. Plus when trying to login it would be interesting to see what happens in the console of your browser.
I’m able to login and i can write a chat with other users. When i start a video call i can see my own picture. As long as the other user havn’t answered the video is ok
that is expected for the old webmeetings. For video calls to work you need to have a turn server configured. A turn server is only automatically configured in the new Meet.
