In the App Settings section of the AppsFlyer platform, you can define a URL for iOS 10.3 fallback.  Any clicks on tracking links with this defined, fallback to the URL if the user clicks Cancel.  Defining this fallback URL ensures that all live tracking links are able to fallback properly without any additional changes to the link.
