App developers that want to leverage Apples install/converison attribution API SKAdNetwork need to update their apps for iOS14. An example implementation of SKAdNetork can he found here: https://github.com/singular-labs/Singular-SKAdNetwork-App. Apps that display advertisement have to include each advertising partners Apple issued id in the Info.plist.
