How has the App Tracking Transparency Framework (ATT), introduced by Apple in 2020, affected advertisers?

1. It has meant permission for tracking has to be sought, so it has led to a significant decrease in the number of identifiable users.
2. It has meant that a user’s Identifier for Advertisers (IDFA) is completely blocked so there is no tracking available
3. It has allowed advertisers to track more data about the user

Correct Answer :

• It has meant permission for tracking has to be sought, so it has led to a significant decrease in the number of identifiable users.
