IOS 10 mail puts messages threads in seemingly random order
Since the IOS 10 Update email message threads on my iPhone 6+ are in a really weird order. There seems to be no real order to how the messages are displayed once you click on the thread.
The first message in the thread seems to be randomly placed under some of the replies, and occasionally the entire thread will be under one of the replies as if the message breaks were not detected.
I have Enabled the "Most Recent Messages on Top" setting which has meant the last message and your entry point to the thread is at the top (rather than in the middle with this setting disabled), but the message order still has the above quirks.
The issue is the same in my Office 365 mailbox and Hotmail.
iPhone 6 Plus, iOS 10
