**Description** Gallery view of the Zoom Meeting SDK not loading. Resulting in video switched off everytime screen share is started. Implemented : Cross-origin isolation overview zoom .us/docs/sdk/overview/websdk-gallery-view/#implementing-cross-origin-isolation FOR FIREFOX : Version 108.0.2 (64-bit) Validation from firefox console: typeof SharedArrayBuffer === ‘function’; true crossOriginIsolated; true FOR CHROME : Version 108.0.5359.125 (Official Build) (64-bit) Validation from chrome console: typeof SharedArrayBuffer === ‘function’; true crossOriginIsolated; true It’s still switching off video when you start the screenshare: tested on firefox and chrome both. **Browser Console Error** FOR FIREFOX : Version 108.0.2 (64-bit) Your browser doesn’t support gallery view. To use gallery view, use Chrome/Chromium browsers and SharedArrayBuffer.
