Hi. Is anyone else seeing intermittent issues with a blank screen when joining/starting a meeting in websdk. We are on 1.9.9 and will update soon to 2.1. It is a library load issue delay I believe and so if anyone has resolved, would be interested as to how you fixed or if a known issue, etc. Thanks ---

Greetings, @gdrums, Thank you for writing us. Camera issues with the Web SDK may be related to SharedArrayBuffers and cross-origin isolation. [It looks like you are already aware](https://devforum.zoom.us/t/websdk-lost-top-rt-gallery-spkr-change-view-button/61487) of this document linked below but wanted to link it here for others looking to resolve the described behavior : > **[Improve Performance in Chrome - Overview - Zoom Software Development Kit...](https://marketplace.zoom.us/docs/sdk/overview/improve-performance)** > > Improve Performance in Chrome > > > > In the Chrome browser, our Web SDKs use an API called SharedArrayBuffer to deliver a better experience to the end user,... Let me know if this helps. Best, Donte ---

Yes ty. This was such a rush to fix, it was oversite that no one had tracked the origin trials cert was not renewed. ---
