Sorry, perhaps bad wording.
The button was in fact removed around 2 months ago with some changes we made to the top nav bar.
It was also in a weird place with the bangs stuff which didn't make much sense.
An idea that was thrown around internally was to put it in general search settings if it were to live somewhere.
It seems we did not really announce this change and it was missed, which is on us and something we should have done.
(with a snippet of custom css that a user could apply if they wish to hide it)
I will bring it up internally to see what we'd like to do regarding this.
