Hello, we implemented Apple Sign-In in our website long ago, and it worked well. Recently we have found a strange behaviour. The first time we make the request to the /auth/token endpoint we get an invalid_client error. Our client id is com.spicysparks.service.id If we make a request another time with exactly the same data it works fine. We noticed we get this error only when we try a newly generated client secret for the first time.
