I'm having the same issue as of this morning (iPhone 6, iOS 8.0.2). I first noticed it trying to download a new app. I'd tap "Free," then "Install" and it would jump right back to "Free." I tried to update an app or two, tapping "Update" flashed for a second and went right back to it.
I restarted the phone, same result. I signed out and back into the App Store, and now it looks like it will download or update, but it just gets the spinning circle and never progresses. If I force quit the App Store, the apps I was trying to download/update now have the stop icon. If I tap it, it goes back to "Free" or "Update" again. Repeat ad nauseam.
I've seen some posts on Apple's discussion boards, but most of them seem to be people who have been experiencing the issue, and now there's this group of us where this just popped up today. I'm leaning towards what @c613m suggested, an issue with the App Store.
And FWIW, I don't have the WSJ app either.

Nevermind, I'm good now too. Must have been an App Store glitch/outage.
