Corporate email not popping up with notification when screen is locked

[AC Question]

Received marshmallow update. Now my default email app which I am using on a corporate account no longer puts the mail symbol on the locked screen. Sound plays but no symbol like before beneath the clock. K9 email works fine. Any thoughts? Earased the account and reset it, cleared caches and data etc.

Which email app is this? Oops. The default app. Which device?
