Not able to save new changes on Facebook Dev account due to new "User Data Deletion" policy

Priority: High
Request: How to fulfill FB’s User Data Deletion ?
Project ID: onlinecourseappblue-15214

Staging Link:
Additional Info: We are using Facebook as Social login, but I guess recently FB added a new policy for letting users delete their own data from the app and without it they won’t let me save new settings until that is fulfilled. So has anybody gone through this or faced it recently ?
