Hello. I have a third-generation iPad with iOS 9.3.5, and I tried the method of copying and pasting the Atari Greatest Hits app to be able to use it with the accessory that was sold, however, the app appears on the home screen, but it is "installed" up to an average of 1/4 of the download, or even 1/2, but it goes up to that point and soon after the app stops installing and soon after disappears from the home screen. Does anyone know what the reason for the conflict might be? I really need this app.
