So far web browsing is my favorite thing in iOS 11. I’ve turned on Reader View for every page that supports it and browsing is fast and ad-free. Tack on the built-in tracking blocker and it’s an excellent experience.
To turn on Automatic Reader View go to Safari and tap and hold the icon to the left of the URL. (It looks like a paragraph of text.) You’ll then be given the option to view all sites in Reader View. Welcome to Nirvana.
