It appears navigator.mediaDevices is missing in your browser

If you are on iOS 11+, please use this app with the Safari browser.

On android, you should be good to go with latest chrome or firefox

If you think you meet all the requirements and the app still doesn't work, let us know. We will try to fix it with your help!

Kindly allow camera access when prompted - the application needs access to the camera

Also remember that camera access is not allowed in browser private mode, so the app won't work there.
