Does not detect card details when device is in landscape orientation. The camera and assist-lines show up fine but it never detects the card details.
This is mainly an issue on iPad where the device would often be mounted sideways.
I noticed the demo app forces the app to be in portrait mode, which could explain why testing has missed this.
Maybe related but it also has the exact same problem if you make the container view for the camera non-square e.g a rectangle of 2:1 ratio. So far I have stuck to a square view for the camera in any orientation to be safe.
