Summary: Improves the mobile Troubleshooting experience and fixes issues with subsession participant assignment, remote control, and self-video rendering.

Changed

  • Optimized the Troubleshooting tab UX on mobile devices. Added a loading indicator so users get feedback while the diagnostic report is being generated, and reduced the overall waiting time before the report can be downloaded.

Fixed

  • Issue where participants who were not assigned to a room before a subsession started would not appear in the unassigned participants list after the room was started.
  • Issue where the controlling side was stuck showing “Remote control screen is not ready” and could not start remote control.
  • Issue where self-video rendered with a height of 0 when running without SharedArrayBuffer (SAB) and WebRTC, by ensuring the video DOM element has an explicit height attribute set.
