after dozens of attemps the only message we get back from the certification team is:
"Unfortunately, your skill has not been published on Amazon Alexa.
We consider a variety of factors as we evaluate each skill, including the customer experience offered through the skill and compatibility with Amazon Alexa. While our goal is to offer a broad and compelling assortment of skills to Amazon customers, not all skills will be made available on Amazon Alexa.
Please do not reply to this e-mail."
so what is wrong? No feedback. No feedback from the office hours. Really bad support.
