Hi

I have created a Netsuite integration in my application and took it to production. I am able to login and receive access_token and refresh_token when I try connecting with the same account that was used to create the integration record/app, but when a customer of mine tries it, we are not receiving the callback to our redirect URI.

These are the steps on our flow:
→ User gets redirected to Netsuite login screen
→ User logs in and is taken to the access screen
→ User accepts the access screen and gets redirected to our application without us getting the redirect callback. We know this because our logs has redirect callbacks that we tried using our account but none from customers.
