ARKit Body Tracking Sample: Wrist joints (left_hand_joint, right_hand_joint) are not updating

Hi,

On my iPhone 12 Pro Max (iOS 16.2, Xcode 14.2), I'm noticing that the body tracking sample produces ARBodyAnchors whose wrist joints (left_hand_joint, right_hand_joint) transforms never change. For example, when waving my hand or twisting my wrist. Other joints work (I haven't checked digits, however).

Has anyone experienced this? I'm not even sure how to begin debugging this head scratcher.

Thanks,

Bart
