Instagram 6 - Is It Just Me?

I read the news about Instagram 6 yesterday and was excited to try it out. When I look at the app in the iTunes app store it shows that 6 is latest available version and that it was available yesterday (June 3rd) but when I check for app updates I don't see that I can download an update and neither can my wife.

Is it just me or is there an issue with Instagram pushing out the update to version 6?
