Don’t you hate it when you start to download a song file, or a podcast, or an app and it just sits there, mocking you? When the little progress bar just refuses to move, no matter how you scream at the front of your magical iOS device? Yeah, me, too.
One way to fix this problem with apps is to tap the icon to stop the download, and then tap it again to resume the download. If that doesn’t work (and it won’t with a media download), then you’re not out of luck. There is another way.
