Is this a known issue? I can have an email thread/discussion ongoing for months but every time I get a new reply, I'm taking way back to the beginning or near the beginning as messages I've read have been marked as unread. For every email discussion I have, I need to scroll to the top to see the latest response. It gets aggravating when you spend as much time on email every day as I do. Is there something I'm missing? I can go through and mark every message READ, but with the next response, they're all UNREAD again...
