AT&T Upgrade App

So I just noticed the ability to upgrade from the Att upgraded app has now gone or me. Being curious I called att. The representative told me the information they have is due to updates rolling out for the application upgrading using the app will not work this entire week. Pretty annoying. Wondered if anyone else noticed this? I think I'm just going to upgrade through the apple store now. Just thought it would be nice to use att own services lol
