I'm having the same issue with the majority of my apps after a hard reset and a fresh start. None are appearing in the Notification+Actions area in settings.
I've never had a problem like this after resets in the past, but I did do one thing differently: I restored my apps, settings, etc from a backup during initial setup (I usually don't). I'd bet money there's bug with that process.
Soft reset and reinstalling the apps does nothing.
If anyone has suggestions, I'm all ears. I have a feeling I'm looking at a hard reset, though....
