What is the smallest size of the image that Hololens 2 can track? I am trying with image target of size width: 0.0565 and height: 0.04725 (unity unit) and it doesn't work. Don't have bigger flat surface on the object to make the target larger.
The same image target works great on Hololens 1 and vuforia image target version 6-2-10 in Unity 5.6.
Do I miss anything? Thank you
