It does look very nice - a lot better than it did before. However, as you said, it is glitchy. More glitchy than the previous version. For example, when I sign in, the default Online ID (my SSN) is one I haven't used for over a year. I have to click on "view more" to see my current Online ID. I wish the default Online ID was the one I actually use. Other glitchy stuff is the very slow animated moving of pages.
I just noticed it is the same as the web site still!! But only cause the website was updated also- what's the point of the app?
