I'm using the .lastSuccessful macro to access the latest build. This works in almost all cases. On an iPhone 5 running iOS 7.0 though, the exact same URL accesses the second most recent successful build rather than the most recent. I know this is an oddly specific case. It works just fine on all of our other iOS devices and from a web browser on the other machines we have here. The only difference I can think of would be the user agent string, but it seems unlikely that that would affect it in such a specific way. I'm wondering if anyone else has experienced similar behavior.
