What happens is you simply toggle the keyboard field off /on in th the same or a different app, a simple albeit slightly annoying fix.

But in general, there is no giant improvement, none of the major ones are even competent enough to figure out a grid of numbers is better than a row, but Apple is even worse - it doesn't even let you type a number on long hold, for some reason thinking that a letter ų you'll never type in your English life is a better alternative

To me, not being able to type in numbers easily is a permanent suffering, though ok, not the end of the world

And unfortunately don't think there is a single swipe keyboard that's properly customizable to fix those glaring issues...
