Fix Weird Email Flows in IOS 10 With the Settings Switcher
For some reason, the Mail app in iOS 10 changed how email threads work. Now the oldest message appears at the top, which doesn’t really make sense to most of us, unless you like scrolling through large blocks of text for fun. Macworld shows you how to fix this.
Go to “Settings”> “Mail” and in the “Streams” section, change the position of the “Most recent messages on top” switch to “On”. This will revert it back to the previous sane behavior, with the newest email in the thread appearing at the top and then descending in reverse chronological order.
