For our app (3074457347393893408; status “Draft”), we go through the OAuth flow, and receive an access token.
Yet, the token is expired: “expires_at” is the current timestamp and “expires_in” is set to 0. We also don’t receive a refresh_token.
Interestingly, the option “Expire user authorization token” is deactivated in the admin UI.
Do you have any advice what might cause this?
