Hey @anhnt, Thank you for reaching out to the Zoom Developer Forum. So far, I haven’t been able to reproduce this issue on my end when using the latest version of Chrome. Please test using a supported browser as the [Cốc Cốc](https://coccoc.com/en) is not supported by the [Web SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/web#zoom-web-sdk). You can learn more about our browser support [here](https://marketplace.zoom.us/docs/sdk/native-sdks/web#browser-support). Let me know if you have any questions. Thanks, Max ---

Please confirm if you see this issue when testing with the [Sample Web App](https://github.com/zoom/sample-app-web). This will help me to demonstrate the issue to ou engineering team or if you don’t see the issue there, it will help us to narrow down the cause. If you don’t see the issue with the [Sample Web App](https://github.com/zoom/sample-app-web), are you able to provide a public git repo of your code so that I can test the issue on my end?
