Bug CommonUsages.deviceAcceleration bug on quest2?

Hi
On my quest 2 If I execute this code in the update:

Code (CSharp):

1.  
2. InputDevice headDevice = InputDevices.GetDeviceAtXRNode(XRNode.Head);
3.  
4. Vector3 acceleration;
5.             bool accelerationSupported = headDevice.TryGetFeatureValue(CommonUsages.deviceAcceleration, out acceleration);
6.             string accelerationstring = acceleration.x.ToString() + "," + acceleration.y.ToString() + "," + acceleration.z.ToString() + ",";

I get ALWAYS 0,0,0 and to me seems a bug...
Also because accelerationSupported is ALWAYS true...

there lines:

Code (CSharp):

1.   bool userPresent = false;
2.             bool presenceFeatureSupported = headDevice.TryGetFeatureValue(CommonUsages.userPresence, out userPresent);

Work as aspected

 

FYI seeing the same running Unity 2021.3.15 builds on Meta Quest 2
