I have setup a account linking for our home skill, but while testing we noticed that alexa is not sending client secret at all, and that's the reason our skill is not getting linked. Any reason of this kind of behavior?
Note - My backend configuration is correct because we are have the exactly same setup for alexa custom skill and google skill (oAuth2.0) and it's working there (skill is sending client secret and we are able to provide access and refresh token).
This is my application id - amzn1.ask.skill.af1ac55f-8f35-400e-b9d3-e045b9c40e46
more one is - amzn1.ask.skill.9fe1df64-c8ed-4486-831e-e20c63bf2467
