Hey @arfa.ahmed

Did you set the `enforceMultipleVideos` parameter when calling `client.init` method? If set to true, it means multiple videos can be rendered on the same canvas without SharedArrayBuffer.

Thanks  
Vic

Yes, `enforceMultipleVideos` is set equal to `!window.crossOriginIsolated`. However, only the self-video is rendered on a single canvas, while other participants show a black screen.
