The long-lived-access-token expires in 60 days. We need to renew this token before it will be expired. We tried to follow the documentation: https://developers.facebook.com/docs/facebook-login/guides/access-tokens/get-long-lived It looks like calling the API endpoint with "fb_exchange_token" parameter generates new token but it has exactly the same expiration date as the old one.
Can you please provide the correct way of renewing access token?
