Hi, Our app is built with the iOS 26 SDK and sets UIDesignRequiresCompatibility to YES in Info.plist. On the same app binary, the system keyboard has its legacy appearance on iOS 26 but the new appearance on iOS 27. Could you clarify: Is this expected behavior or a known issue? Should this key preserve the legacy keyboard on iOS 27? Is there a supported way to restore the iOS 18-style keyboard without implementing a custom keyboard? Thank you.
