Question

I use Xamarin.Forms, but I do the necessary actions on the iOS side, but Facebook does not verify the update.
and I'm new to this problem I had no such problems in advance.
I using plugin: Xamarin.Facebook.iOS (4.39.1)
SDK is up to date, although I have done all the necessary applications, my problem is not solved.
