Hey @jefferson.ribeiro

Could you check whether `SharedArrayBuffer` is available on the production site? The sample app is enabled by default on the local environment.

If you have difficulty enabling `SharedArrayBuffer` on production, the `enforceVirtualBackground` option in `client.init` method will address the case on Chromium-like browser.
