I have a project that's been in development against iOS 7.1 and now with the iOS 8 update, the Detail side of the Master Detail view is entirely unusable for any view that opens in landscape orientation. Notice in the image how far off center the header bar text is. Also, on this page there is a ToolbarItem that's clearly not reachable.
I'm actively re-downloading the iOS 7 emulators since Xcode seems to have replaced them with the iOS 8 emulators. I don't know if this is a Xamarin.Forms issue or if it's something I can fix in code, but it's sidelined this project until we can get an answer or work around.
Thanks for the help!
