Figured out the camera issue!
It seems Hangouts (in Chrome and Explorer) and the QR scanner app don’t work with the tablet rotated! Rotate the tablet so the left side (when viewed with USB-C port is at the bottom) is at the bottom and the camera is correct but rotate it the other way and the app rotates but the image gets flipped and upside down so think that’s a bug?
The windows camera app works in every rotation angle.
