Resolution Note:
The APIs we're using for operating webcams on iOS and Android don't allow more than one integrated webcam at a time to be active. This is in fact a limitation of earlier multi-camera devices. This is now supported in more recent devices, but adding support for this would involve a rework that is not currently scheduled.
However, the current behaviour is admittedly surprising, we will update the documentation to make this clear.
