Read messages changed back to unread?
Lately, some of the messages in my inbox, that I have previously opened and read, are appearing as unread, usually the next day or at least a few hours later. Once a message is read or marked as read, and the blue dot is no longer lit up, that should be the end of it. How and why are read messages changing back to unread, with no input or action whatsoever on my part?
