Difficulty getting HockeyApp working

I've followed the instructions for the HockeyApp integration (honestly it's just cut and paste) but I never see any notification that a crash has occurred (I am testing with a crash that I'm doing intentionally).

http://components.xamarin.com/view/hockeyappios

Anyone else have this issue? Here's what I've done:

1. Created my HockeyApp account
2. Added the component to my project.
3. Added the HockeyApp.Setup.EnableCustomCrashReporting (() => { ... } code to my FinishedLaunching method.
4. Made sure that I uploaded my IPA to hockeyapp
5. Made sure that I was using my generated AppId
6. Tried explicitly setting manager.CrashManager.CrashManagerStatus = BITCrashManagerStatus.AutoSend.

No luck.
