Hi. I recently received my iPhone 5 with iOS 6 and have added an exchange mail account. I have seen many discussion regarding issues with push, but push is working fine for me (so far!). The issue is that I am missing the blue bar across the bottom when in mail, which means I am also missing the button to compose a new mail message. The problem extends to when I am in an email; I am unable to create a Reply message. Has anyone seen this issue? Any suggestions?
