Please try launching iFrame Debug from the WebView to ensure all of the necessary permissions (camera, gyro, etc) are being propagated to the page.
If permissions on the page are missing/unresponsive, you should ensure permissions are accepted on the app level and on the WebView itself, which we don’t have documentation or guidance on as it’s on the native app side of things.
If all permissions appear to come through via the link above, the WebView should be configured correctly - in this case, please pass along information from both device-compatibility and device-estimate.
