Facebook Privacy Policy

Hello there, not sure if this is the right place to post but
I have published an iOS game that uses Facebook SDK. Problem is when I create the Facebook app they ask for a privacy policy. It was working fine until yesterday. I tried to paste the URL of the app in iTunes like all the times I did in the past and a window with an invalid URL message pops up when I try to publish make it live.
I also tried to generate my own privacy policy using an external service ( i paid $10 for it ) and put it on my website and didn't work.

Anyone having a similar issue? Any help will be appreciated
