Path Input Didappears

I was joyfully using what I thought was the best swipe keyboard for the iPhone.
2 days ago it no longer functioned. Despite following detailed directions that was supposed to let the Notes App take full advantage of the swipe style keyboard, Notes just doesnt recognize the change made in settings.
I know I only paid about 2$ for Oath Input, but what is their excuse not to support it?
Obviously, I was on the wrong path.
