Which Web Video SDK version?
“version”: “3.13.2”,

We investigated the macOS Chrome Zoom failure (black preview, mic/camera spinner, stuck on “Joining Meeting…”).

It works in other browsers, so issue is Chrome-specific.

  • It works in non-Chrome browsers (Safari/Firefox), so the issue is Chrome/Chromium specific.

What we checked and changed

  • Verified runtime indicators in Chrome:

  • Initially had crossOriginIsolated=false, SharedArrayBuffer=undefined.

  • Added cross-origin isolation headers in app setup (for test env):

  • Cross-Origin-Opener-Policy: same-origin

  • Cross-Origin-Embedder-Policy: require-corp

  • Re-tested and confirmed:

  • window.crossOriginIsolated === true

  • typeof SharedArrayBuffer is available.

  • Upgraded Zoom SDK references to newer version alignment (3.13.2) in app config/references.

  • Despite these fixes, some Chrome sessions still hang at Join.

Current interpretation

  • We fixed one major prerequisite (SAB/isolation), but there is still a second Chrome-specific failure path.

  • Since hotspot/incognito tests still reproduced in affected case, not only a simple extension/network issue.

  • RTC dump shared (getUserMedia: [], PeerConnections: {}) suggests failure can occur before full RTC setup in Chrome.
