Hi guys,
I need your help here.
I was troubled by Facebook click-loss (it reached to 90%) from yesterday and got a feedback today from FB as below:

It’s a huge blow to me and I am trying my best to figure out the problems.
Is it because of ads complaints or any other things?
This seems to happen without reason.
But could also be due to you letting clicks get geo-redirected (and ads disapproved), leading to FB blacklisting the domain or specific link.
I would CNAME another domain to your tracking system and move on.
