Since last few weeks our FB integration is broken, our app and website having option to login using FB, we were pulling FB token and public profile info such as name, email but now seems FB has restricted our app, and got message "We've restricted this app for violating the Facebook Platform Policies."
We double checked updated policies document and it seems nothing is there which can break FB policies, we are struggling to identify exact reason, we raised Appeal few weeks ago to FB but no reply, now we all our live users are stuck they are not able to use their account anymore in our platform.
Is there any way to identify exact reason, based on which parameters FB has blocked our app?
