When I read a message, your app automatically moves it to Old Mail. STOP THAT !!!! If I wanted it in old mail, I would put it there myself!
STOP automatically putting my read messages in Old Mail. STOP IT !!!! Don't do it anymore!!! There is no reason you can give me to justify it !!!
Automatically moving read emails to old mail should be an option and not forced. It makes the app unusable for some. Allow read emails to stay without being moved.
