Recorder user couldn't join the meeting (realtimeSubscribeToAttendeeIdPresence was not triggered) in Chrome & Edge

What happened and what did you expect to happen?

What happened? I used the browser demo app

1. I started the meeting and joined as a regular user
2. And then I joined the meeting as a recorder user by appending record=true query parameter in the URL.
3. Meeting Recorder attendee was not listed in the roster for both users (realtimeSubscribeToAttendeeIdPresence callback was not triggeed)
4. Also attendeePresenceReceived was not received for the recorder attendee

This issue was not occuring in Firefox browser. Occuring in Chrome & Edge browsers.

Expected result:

• When Meeting Recorder user joins the meeting, realtimeSubscribeToAttendeeIdPresence callback should be called and the recorder attendee should be listed in the roster.

Hi @vishnusankarkrishnan , thanks for bringing this up. I can reproduce this issue in Chrome, Edge and Safari. The issue seems related to autoplay policy. By enable the autoplay policy for the site, the issue is gone. We will look in this issue to figure out the rootcause. Could you please try the below steps to avoid this issue for now?

• Chrome: Preference - Privacy and security - find the demo site - Sound - Allow
• Safari: Preference - Auto-play - find the demo site - Allow All Auto - Play
• Edge: Preference - Cookies and Site Permissions -All permissions - Media autoplay - add the demo site

Let us know whether this helps. Thanks!

Hi @vishnusankarkrishnan, we got a same issue #1715. We find the recorder is blocked by the AutoPlay policy. So instead of enable the AutoPlay policy like we mentioned earlier, you could add some interaction to let it pass the AutoPlay policy. For example you could add a join button when the URL contains record=true and then the recorder could join the meeting after clicking the button.
