I want to upgrade my office 365 from personal to home. Since I purchase it through iTunes I apparently must go through that way to do it. I can't find the 'in-app purchases' to upgrade. Or more to the point, the listing of in-app purchases when you finally get there is not an active list link so not 'button'. I canceled my renewal/subscription but that won't take effect for several days. Is there anyway to get Office 365 upgrade NOW?
