Hi to all! I have a problem: I run the code as it comes from the zip file, [https://developer.apple.com/documentation/arkit/content_anchors/capturing_body_motion_in_3d) Xcode makes the built, no error, and sends the app to my iphone. The problem is that nothing appears in the Ar view, I can't see the robot.usdz, inside the appledeveloper code. I'm using iPhone 12 pro, iOs 15 beta 3 and X code 13 beta. I've updated everything, so that may be the problem? Is lidar on as default? I don't see any code about lidar inside the code from the zip. Why doesn't the robot even appear to me? Apologise for all that question maybe almost off topic, but the situation It's really frustrating, so any help is very appreciated :)
