Trying to enter App Domain for our App Store URL (as described on Step 1>App Domains here: https://developers.facebook.com/docs/app-events/getting-started-app-events-ios)

But when we attempt to enter the App Store URL, it generates an error based on it being an App Store address.

Error message reads: "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: apps.apple.com"

So how can an App Store address be entered if apps.apple.com generates an error?
