Using Model 01 with iPad Pro: the on-screen keyboard remains on screen

My Model 01 just arrived, and it’s been a treat to use so far. I’m just running into one issue, when I try to use it with my ipad: the on-screen keyboard remains on screen when the Model 01 is attached. I’m still able to type with the Model 01, but it’s a bit of a nuissance having the iOS virtual keyboard taking up screen real estate. I haven’t had this issue when I’ve used any other USB keyboards with the iPad, and I’m not sure what’s causing this (maybe it’s just a matter of registering the device’s identifier with Apple?). Any assistance would be appreciated. Thanks.

Can you try pressing Left Fn + Esc + Shift, and see if the on-screen keyboard remains shown?

Yeah, it doesn’t appear to make any difference.
