When entering address data, I can't scroll the window to see other fields.
In this window, you will have to use the button to access the other fields. Scrolling by swiping up/down will not work here. This is a problem we encountered with scrolling editable fields but we don't yet have a workaround. This also happens in the Name section of the Person Info window.
Note: currently you can not edit the "email address" or "web page" fields.
