#### Hello,

I’m experiencing intermittent issues where some users are unable to activate their microphone and/or camera when joining sessions through the browser using the Zoom Video SDK.

The issue appears to be random and does not consistently affect the same users. It has been reported across all major browsers (Chrome, Edge, Firefox, Safari) and across multiple devices and operating systems, including Windows, macOS, Android, and iOS.

Users have confirmed that:

1. Browser permissions for microphone and camera are properly enabled

2. Device-level permissions are granted

3. No other applications are using the microphone or camera

Despite this, the microphone and/or camera sometimes fail to initialize within the browser session.

I’m using Next.js, and it seems that `startAudio()` and `startVideo()` do not respond when the issue occurs. No error is thrown.

Here is the relevant code snippet:

const client = useRef(ZoomVideo.createClient());  
const mediaStream = client.current.getMediaStream();

await mediaStream.startAudio();  
await mediaStream.startVideo();

Has anyone experienced a similar issue or can suggest possible causes or debugging steps?

Thank you in advance for your help.

It seems these are not valid Zoom session IDs. You can find the correct ones in the Web portal under **Dashboard → Past Sessions**.

Thanks

After analyzing the logs, we found that most of the devices experiencing the issue are using iOS 26.2. This version has a known issue, which Apple has already fixed in iOS 26.3.
