I have a skill in certification and it was rejected because the utterance "shut up" was specified in the AMAZON.CancelIntent, and i have a YesIntent which contains "yup" as a utterance. now the reviewer rejected my skill because he said "shut up" but my skill thought he said "yup" and actioned the yesIntent instead and prevented the skill from exiting.
I have amended my skill and remove "yup" from the utterances of the YesIntent, now my gripe about this is that this should not have even happened shut up is two syllables and although sounds like yup, however my skill failed in all 5 regions which means that alexa failed to recognise "Shut up" five times and mistook it for "yup"
I am sorry amazon. i reject your certification output as a failure of your software and not mine ;)
