Recently I down loaded a movie from I tunes onto my iPad . I took another of my iPads , signed out the existing apple i.d. And signed in my apple I.d. Which was used to purchase the movie and downloaded it on my second iPad. It worked but when I signed out of the iPad and my mom signed back in with her apple i.d. The movie was no to be found. How can she access the movie. FYI , I bought the iPad, and the movie.
