I've created a skill that has got the Amazon.StopIntent and Amazon.Cancel intent. Cancel functions fine. Stop is never called.
It *is* called if I say. "stop, stop". Even though I have only "Stop" has the word stop in the utterances.
So, I open the session by saying, Open <invocation>, which causes the welcome and puts it into listening mode, but then I say "stop" and I only get the beep - no endpoint call, which means no logs in cloudwatch. If I say, "stop stop", then I get the endpoint call.
Anyone else having trouble with "stop?"
