Eye tracking hololens 2

[adammartiska]

Hello, I am trying to implement eye tracking in my Unity UWP Hololens 2 app with the help of Mixed Reality Toolkit. I wanted to implement the eye tracking, but I still get only data from head tracking - for example for CoreServices.InputSystem.EyeGazeProvider.HitPosition . After starting my app I logged 3 booleans to find out if my configuration is valid, and I saw that IsEyeCalibrationValid returns null. I did my eye calibration on Hololens 2 device and after initial start of my application I also got asked about permission to access eye trackers and microphone. Does anybody know why this configuration could be invalid? (I am guessing that is the reason I am getting data only from head gaze)
