UPDATE: This has been resolved (11/17/2011) All update buttons should now work.
For our eBay users, we are experiencing a problem with the "update" button on the Accounts page. We are aware of this problem, and are working on fixing it as soon as possible.
In the meantime, there is a way to update all your account at once.
On the Overview page, on the left bottom of the screen, you should see a "Refresh all" account. Press this button, and it should update all your accounts.
