Surface hub on screen KB predictive text

I've noticed some of my surface hubs in my organisation now have the predictive text feature on the onscreen keyboard.

I've followed the settings for this; 

Press the Windows + I keyboard shortcut to open the Settings app.

Click on the Time & language tab.

Navigate to the Typing section.

Click on the toggle button next to the Show text suggestions when typing on the physical keyboard option.

However they do not work.  

Why has this been rolled out to Surface hub MTR devices?

The only way I can work on these devices with this feature is using a physical KB.  Has anyone seen this and found a resolution please?  

Again no idea why there's no testing on the roll out of features for these devices.

Although I've seen Edge can be added via the Teams admin portal but other apps like Maps are still not available.

yours faithfully
