The first link in the nav bar points to the frontpage but it's not shown as active and that isn't apparent from the link text either, so it seems like a broken link.
The "Open app" & "Get started" links break the browsers back button. These are the first links I'd click, and at this point I have no idea what I'm even signing in to so I'd want to go back and explore a bit before... but since the back button doesn't work, I'd just close the tab and forget about it :)
I would also throw a lock icon on the button to signal the fact that login is required.
