**Description**  
There are 2 people joining the same zoom session with the video On.  
The third person is able to see those 2 people’s video who joined earlier rendered on his canvas nicely. Then, the third person leaves the zoom session. Now, the third person only sees one person video rendered (instead of 2 videos) after joining the same zoom session again.

On the console log for the second time rejoining the zoom session, I see the following errors (10 times)  
**SharedArrayBuffer will require cross-origin isolation as of M91, around May 2021**

**Which Web Video SDK version?**  
Video SDK 1.0.3
