Our iPad application opens in portrait and landscape modes in the test environment. Once deployed to the iPad device it only opens in portrait orientation. Opening in Landscape just flashes the default UILaunchImageFile .png and closes. Once the application has been opened in portrait orientation rotating to landscape works without issue. iOS key UISupportedInterfaceOrientations is set for all 4 orientations. UIInterfaceOrientation is set for UIInterfaceOrientationLandscapeLeft. Is this a known issue? Are we missing something?
