So today I went to download this app that was free and when it showed up on my screen to begin to download it says "loading" then then the app disappears and won't download. I also had some apps i had to update and then when they began to download then stopped and didn't fully download. I tried it again and it worked and they downloaded the updates. Anyways what is going on and why won't this free app download that I'm trying to get. It's a movie app
