One of our app had problems we turned it to the development mode. And we have been writing the game all over. It is about to finish but I can not enter Facebook Web Games Url.It was giving error saying "App domains must match the domain of the Facebook Web Games URL (https), Mobile site URL, Unity binary URL, Site URL or Secure Page Tab URL. Please correct at least one of these domains: oyunzade.com" so I removed al lthe domains but I could not re enter them.

I am using graph api explorer for /page/search endpoint but even after adding the pages_read_engagement permission from the list of drop down permissions I am getting the error:
"message": "(#10) This endpoint requires the 'pages_read_engagement' permission or the 'Page Public Content Access' feature or the 'Page Public Metadata Access' feature."
What other necessary permissions are required for this?

I have a question about creating an advertising campaign. I've searched through a lot of information and tried many times without success, so I have to seek help here.
When I try to create an advertising campaign, I'm prompted with "You can’t create a new campaign with this iTunes App ID as it’s already being used." I did indeed use the same iTunes App ID to create a Facebook app in the developer account before. However, I can't log in to that account anymore, so I can't delete the binding relationship between the app and the iTunes App ID. I'd like to know if there's a way to revoke the authorization of other Facebook apps for this iTunes App ID. I can provide all the evidence to prove my absolute ownership of this iOS app (iTunes App ID). Thank you!
