Spotlight multiple speakers does not work and some users saw blank black screen

Description
Is there a known issue or workaround about not showing multiples pinned speakers, and some black screens / audio issues when doing this? Maybe we are using a wrong configuration?

Error
We are pinning / spotlighting multiple speakers in zoom, but only one panelist is showing, we can’t make it to show all of them. Also, some users are experiencing black screens and audio issues when this happens.

Which Web Client SDK version?
1.9.6

To Reproduce(If applicable)
Steps to reproduce the behavior:

  1. Start a webinar
  2. Make other users panelists
  3. Pin multiple panelists (as little as two)
  4. Only one panelist shows.

Screenshots
[I can add only one screenshot on new user]
One user showing when multiple are pinned

Device (please complete the following information):

  • Device: Dell XPS
  • OS: Windows 10 21H1
  • Browser: Chrome
  • Browser Version 89

Additional context
Some attendees couldn’t hear the audio, and they weren’t able to open their mics.
