I made a new Unity 2020.3 (LTS) project with Vuforia sample for Hololens 1 and 2. On building and running the project as is on Hololens-2 (ARM64), launch Image Targets scene from the Menu and looked at the Astronaut marker. The info panel shows that the target is being 'tracked' 'normal' or extended tracked', but I do not see the Astronaut Augmentation. This is the same case for other image targets and the Vuforia Mars Object target. The augmentations do not show up. The scenes work as expected on the Unity Editor.
Can you please help?
