Date picker in forms is very difficult to use (you can only change 1 month at time)

Hi all

In forms the date picker only allows users to change the date one month at a time. And for dates of birth for example this leads to pretty much unusable functionality.
Yes, on a desktop you can type in the date, but this is firstly unintuitive, and worse, on mobile this does not work - rendering a date picker for date of birth as completely unusable.

Any idea why the date picker is like this or ideas how to resolve it?
