I'm using Desktop Central MSP and have just begun to explore the MDM feature set.  I started the 3 step process of creating and Apple APN but, am stuck.  After completing the first step, the one in which I enter my company name and email address, I moved on to the second step.  At that point I realized that I had typed the email address incorrectly in step 1.  Unfortunately, I can find no way to go back from step 2 to step 1 to fix the mistake.
