Why the App Was Rejected (Guideline 4.0 – Design) Apple rejected the Mac version of LingoBoard under App Store Review Guideline 4.0 (Design), citing a user experience issue related to window behavior.
According to the review feedback, when the user closes the main application window using the red close button in the upper-left corner, the app remains running in the background, but there is no clear way for the user to reopen the main window from the menu.
