I think this may be a temporary eBay issue. When I visit My eBay, every section says, "Some of your information is not available at this time. Please try again later." This is true of two of my three IDs, so I don't think it has anything to do with the new API version. And I did sign out/back in. Closed/reopened the browser. Signed off/back on the internet. Nothing on the System Status board, however.
