Tapping mail notification or search result opens Inbox

In previous iOS versions, you could tap on an email notification, or search for an email using Spotlight and be able to go directly to the email. Since iOS 8, sometimes when I tap an email it just opens the 'Mailboxes' view of the mail app instead of opening the specific email that I tapped on. It doesn't happen all the time, any ideas?

 

Bump anybody?

 

Anybody? Could use some insight here.
