Mail app crashes constantly after iOS 7
Updated 6.1.3 to 7.0 and native Mail now crashes to home screen anywhere from 0 - 5 seconds after loading, sometimes while the screen is still white (loading) and sometimes a few seconds after I can see and temporarily navigate my mailboxes. Was working fine before - Anyone else have this issue or know how to resolve? Apple, are you aware of this / fixing?
No, I will not restore a backup or reset to factory settings - these solutions are unnacceptable for many reasons.
