  1. Resolution Note:

    Hello!
    Thank you for bringing this issue to our attention. After thorough investigation, we have confirmed that the feet misalignment behavior reproduces with Apple’s ARKit Body Tracking functionality, as demonstrated in their own implementation: Capturing Body Motion in 3D ( https://developer.apple.com/documentation/arkit/arkit_in_ios/content_anchors/capturing_body_motion_in_3d ).

    We recommend reporting this issue directly through Apple’s Feedback Assistant ( https://developer.apple.com/bug-reporting/ ).

    If you still encounter the issue or have further concerns, please feel free to reply to this message, and we can reactivate the investigation as needed!

    Best regards,
    Dianna Spiegel
