@tommy When did this bug show up - what verion and would it effect previous pre 2.+ versions like 1.9.9 and requiring a breaking change needed to fix to update to 2.1.1? What was this bug effecting was it blocking SharedArrayBuffer? Want to determine urgency to update to 2.1.1 and more on this bug and symptoms - would the app also not show the gallery/speaker view button change?

Hey @gdrums ,

The issue of not being able to start your video on Chromium browsers without SharedArrayBuffer was only n version 2.1.0.

We are going to be updating the doc here with a better explanation of what SharedArrayBuffer enables: [https://marketplace.zoom.us/docs/sdk/overview/improve-performance](https://marketplace.zoom.us/docs/sdk/overview/improve-performance)

Thanks,
