Magnetic field data not available for Apple Vision Pro

CMDeviceMotion magnetic field is not receiving when requesting from Apple Vision Pro device. Tried getting data with all for reference frames(xArbitraryZVertical, xArbitraryCorrectedZVertical, xMagneticNorthZVertical, xTrueNorthZVertical). In these xArbitraryZVertical returns deviceMotion.magneticField.field x,y,z as 0. And from other reference frames a nil value.

Note: working fine for iPhone.
