Detect and Track but not seems to track perfectly

[enzyme69]

I tested the project on iOS 12, with ARKit 2.0, seems to work fine:

• detect image
• AR 3D object appears

However, it does not seem to track and maintain the image position, expecting it to stick to the image a bit more accurately.

Wondering if this is a feature of ARKit 2.0 that is not used in the project?
