问题
I've tried the codelab and followed the video tutorial and and just can't make it work. In both cases the app loads, but (a) no motion tracking permission is requested and (b) the device motion does not control the camera.
These labs are super simple and don't contain any code, so I am fairly confident I do not have an error.
