Can't update Account Info in App Store on Mac
I am trying to make a purchase on the Mac App Store and it tells me I need to verify my payment info. I enter my password and it goes in to the Account Information Page. Then if I select 'Manage Payments' it asks me for my password again, and then goes back to the Account Information Page. I get the same if I try to change Billing Address etc. I can't access any of the subpages. Anyone know how to fix this?
