The App Store review in the screenshot used the phrase "ratings nag on the app interface." It did not say "nag screen".

My app does have a ratings request on the app interface, which does not interface with the other controls on the app interface. It does not have a dedicated ratings request screen.

People are just assuming "nag screen" based on the single word "nag", and even that word is questionable in my opinion, but I do indisputably present a ratings request.
