When I swipe through unread emails and then go back to the main email screen, the emails I've just read are in an unread state.
When I swipe though my emails from one to another, there is a glitch where it very quickly moves to the next email and back and constantly repeats until you press back.
I would like to change my settings so that I only ever see all my emails rather than primary, offers, other, but I can't find this setting
