Facebook recently warned us that our app will be restricted due to violation of our Platform Terms and Policies. They asked to provide more information including login credential of test or debugging user.

As response, we provided link to the app and credential of a test user to log into the app through URL. We tested the app and URL using the same credential to make sure it's working, and for sure it was fine.

In spite of all the details we provided, Facebook is still warning us and restricting our app to be accessed by publice. We don't understand what have missed and why it's still complaing about the violation however wer provided a valid credential and valid URL to the app!
