Our access token expires within 24 hours. Alexa doesn't seem to be making a call to the refresh token for our Smart Home Skill. I've verified the message we are sending back validates against the V3 JSON schema and it's included below. What are we doing wrong here? If I disable/re-enable it will work again for 24 hours. Any help is greatly appreciated.
