Apps not installing on iOS6

Just downloaded and am running iOS6. Installed a few new apps and they're all stalling on installation. This didn't happen under iOS5, ever, so I'm wondering others are having this problem and/or whether this is

To be clear, the app icon loads, then in saying "installing" but the blue line on the bottom never progresses. A few times it progresses halfway, then goes back to nothing.

Any help would be appreciated. Maybe the App Store is just overloaded right now?

 

It's been "loading" now for 24 hours, but on wifi and 3G. Confused.
