I have been using TestFlight for several months now to distribute new builds to our beta testers and for the most part I haven't had any problems. As of today however, the app is crashing immediately after launch on all devices - without generating any crash reports, so I have no idea what the problem is.
The app runs fine in the simulator, and runs fine on our test devices if installed directly through Xamarin Studio (both debug and release versions are working). These crashes are only occurring installing the app through TestFlight. Can anyone offer any suggestions as to how I can track this problem down?
