[android-developers] Set up Beta testing

I'm working on a new app that I'm not ready to release yet so I made an entry for it in the play store and uploaded an APK as a beta, then published it.  I created a new google group for my beta testing and added it as authorized, then went to the given URL to opt in as a beta tester and it confirmed that I was a tester and gave me a market link (which looks like the standard play store link for if I had made a public release).  But when I go there it says page not found!   What am I missing here?
