OVRInput.GetDown doesn't work at all on Unity 2019.1.1 (Oculus Go)

Hey, I've run into an issue with unity integration. I'm using unity 2019.1.1 and OVRInput.GetDown doesn't work as in it always returns false. In the meantime, OVRInput.Get works as expected. Before I do any custom implementation of GetDown as a workaround, I'd like to know if it is going to be fixed or if I'm doing something wrong. I know that there are other people asking about this issue but I never seem to find an answer, most of the threads are usually answerless...

as a reference, this is what my code looks like (yes there is an OVRMananger on the scene, as I said, everything works fine using Get while GetDown doesn't seem to work.

public bool InventoryBttn;
public bool InventoryBttnDown;
public bool InventoryBttnUp;

void Update(){
        InventoryBttn = OVRInput.Get(OVRInput.Button.Back);
        InventoryBttnDown = OVRInput.GetDown(OVRInput.Button.Back);
        InventoryBttnUp = OVRInput.GetUp(OVRInput.Button.Back);
}
