Keyboard and Mouse controls don't work on iOS

What is the actual use of the options in game whereby we can use keyboard and mouse? But even according to the default controls binding for the keyboard it does not work? The only thing i am able to do with my keyboard is to type in chat. Is this a bug or there is only certain specific external Bluetooth keyboards that will work with MCPE?

If the default control bindings states that WASD are possible but i'm not able to look or walk around with my current bluetooth keyboard, i'm kind of sure this is a bug? Please kindly enlighten or advise if there is any actions being followed up or it is aware as an  issue/bug. And not just simple put as resolved but iinvalid resolution or no solutions stated? 

 

Looking forward to fixes / replies. Thanks
