I was trying to use Vuforia's Ground Plane feature following this tutorial, only putting a cube on a ground plane though. https://www.youtube.com/watch?v=0O6VxnNRFyg&t=25s
First the DefaultPlaneIndicator prefab has to be manually dragged from Vuforia's prefabs into the Plane Finder object, unlike in the tutorial. I used this automatic mode but it doesn't work. Interactive mode doesn't work either.
When I test it in the Editor nothing pops up when camera shows the floor and I tap the screen. Same goes for when I test it on my phone (Mi 8 with latest MIUI and Android versions).
Here's a screenshot of my work.
Here are the Console logs when I test it on the Editor.
