How do I troubleshoot the updgrade process of my ASUS Transformer to 3.2.1?

I just got a new ASUS Eee Transformer TF101. (Ironically on the day the Prime is officially released/announced. Oh well). It came with Android 3.1 per the Settings page. I tried Settings: About tablet: System Update and am told there are no updates available. I read that 3.2 is available on these devices. (I know 4.0/ICS is still a future thing). How do I get to 3.2 on this device? No obvious downloads on Asustek web page. I am on my WiFi at home, checking mail, downloading apps, etc. So how do I troubleshoot why the Over The Air upgrade did not show an available update, when there has been one available since early 2011 (many moons ago). I am logged in to my Google Account. (I have my Gmail, Google Voice, and Youtube accounts all connecting ok). What else can I check or look at, to understand why the OTA upgrade is not being made available.
