There's a difference between being blocked from innovation and having UX engineers look at something. It is the job of these folks to find out things like this; they don't have blinkers on when it comes to knowing about how the app gets used and how people can fail at things.

It's quite likely that this was just directly shipped given that it's a one-day thing.

Nobody's asking them to stop innovating; you can be more rigorous in your shipping process (which they usually are) without affecting innovation.
