A problem with Facebook ad network

If anyone have experience about facebook ads network please help me:cry:

I’m trying to add my app in facebook ad network but it shows "This app is already being monetized: The app you’re attempting to add is already being monetized by a business."

Actually i had added a property namely “All Social Media” now i have removed it, now i’m trying to add my app in new property but it shows error

I have also contacted facebook but no positive response

That means you have already added the same app with the same package in Another Facebook Account.

You cannot add the same app in multiple accounts !

No bro, i added app in my property that I have removed. I also contacted Facebook!
