How do I fix things when the normal app uninstall process is failing on iOS?

Of course, by holding down on an icon and tap the x lets me uninstall an app. But take a look at this: Here, the Pandora app is somehow stuck at the "update phase". Tapping it to continue download doesn't work. The progress "circle" will get stuck. So I decided to reinstall it. > Translation: > **Delete “”** > Deleting “” will also delete all its data. For some reason it doesn't even show the name of the app. It's just blank. Tapping delete does nothing. So what do I have to do to fix this problem? Running iOS 8, not jail broken.
