I'm try to link my azure environment to Alexa. I'm using Auth Code Grant with HTTPBasic. After entering Authorization URI, Token URI, Client ID and Client Secret, the Link account page in alexa skill redirects to login.microsoftonline.com. After logging in, I'm redirected to skills.amazon.com which says Unable to link account to your skill. For the alexa endpoint, I'm using an Azure Function App. I'm able to get access tokens when testing on Postman. Has anyone encountered any similar issues? Is this a bug in alexa skills kit or Azure AD?
