All you hear about are all the great bells and whistles that are coming every time Apple releases a new beta for a major iOS update, but when the final version finally arrives people with older devices discover they can't access most of the promised new features. Trying to figure out what new features your device supports can be confusing. For example, on Apple's iOS 9.3 preview page it says you can "sort notes by date created, date modified, or alphabetically." This is true, but all the other new Notes features are found within the Notes app, while the sorting feature needs to be setup in the Settings app. New iOS 9.3 users could waste an entire day trying to find the "Sort Notes By" section if they have never used the Notes settings before. If you didn't think to check the Settings app you may have convinced yourself you're going crazy, or that your device doesn't support the new Sort By options.
