I have test skill "amzn1.ask.skill.e7d40df9-88f9-4414-a00d-3763e86b8a16". I can test it from my amazon echo dot but not from my kindle fire tablet (hd 8 2017 recently purchase). Alexa on the kindle fire does recognize my invocation name "Shrikant" but does NOT execute my skill. It takes me to search screen for all the public available skills. In fire hd alexa app i do see my skill enabled.
