Hello there,  
Can you please help me here to understand when this error occurred?  
**JsMediaSDK\_Instance.util.isSupportAudioDenoise is not a function**. The same functionality worked before, but now it’s giving this error, and the user can’t do mute or unmute and can’t hear others voices also.

Thanks and regards,  
Samiran S
