New user to Vuforia and the setup was quite simple and fun! I like the outcome of my work with Vuforia...to an extent...
I have installed and set-up the latest Vuforia with Unity (v2018.3.7, so Vuforia came installed with Unity...).
This video shows you that it works: https://imgur.com/bFYERdp
But it also shows that Device Tracker/Extended Tracking is not working. The model disappears when the Image Target (the book) is out of sight. And I even carried out the correct step! >>> https://imgur.com/9EWHR6K
What am I doing wrong? I can't think of anything as its only 1 step for enabling this feature..?
