I think the 8 categories are a good thing, otherwise if you just activated the camera without choosing a category your screen would be filled with points of interest/locations to the point of being unusable.
Unless I misunderstood your question. You need to choose a category for the camera to switch on.
If I select a category it then shows me a text list of businesses nearby, listed by distance away. Just like if I had used the Local Scout. If I press the side button to go to Camera, it s just the regular camera for picture taking. If I go into Lenses there, there is panorama but not city lense .
I did already uninstall and reinstall city lense too.
