Takedown update LIVE on iOS

Any suggestions for how to get the update button to appear for TSTO in the iOS app store? I've tried pulling the screen down to refresh it (which worked for me once, a while back, but no luck this time). I can see that the game icon, etc. has changed in the store, and I know I can do an uninstall/reinstall to get the update to work, but that's sooo slow, so I thought I'd see if anyone knew of any other "tricks" to try first...
