iOS 13 iPhone Xr editing in mail app uses up too much screen space

Hi,

Using Swiftkey in the iOS 13 Mail app with iPhone Xr, the keyboard now takes up so much screen space that there's not much room for editing the text! I've had to switch off the number row (which I really like) to save space, because the new iOS editing bar/row (whatever it's called), can't be hidden like it can with the native keyboard. Any ideas? Anyone agree this is an issue? 

Also, although I now only have Swiftkey enabled, so that there is no Globe/Global key at the bottom, there is still about 1cm of empty space on the screen between the bottom of the space bar and the home bar/line at the bottom of the screen. Is there any way this space could be reclaimed, I wonder?

Thanks for any ideas or comments.

Wilf
