I want to effect an increase in system-wide font size for both built-in and third-party apps on iOS 9.x. What is best approach between Option 1 & 2 below? Do I need to use a combination of settings from 1 & 2?
Option 1: Dynamic Type slider preferred reading size (under Settings | Display & Brightness | Text Size). Assume this is 'the right way' bur seems many apps do not support this API.
Option 2: Accessibility 'Larger Text Sizes' toggle and slider (under Settings | General | Accessibility). Am guessing this is a more brute-force approach.
