FAQ

Is my video or audio sent anywhere or recorded?

I accidentally blocked camera/mic access. How do I fix it?
Click the camera/mic icon or the lock icon in your browser address bar, change this site's access to "Allow", and reload the page. On mobile, you can change site permissions in your browser or OS settings.
The mic meter does not react.
Make sure the mic is not in use by another app (such as Zoom), the correct microphone is selected, and your device/OS volume is not muted. For external mics, check the connection too.
My camera preview does not appear.
