Navigating the post-IDFA world: All you need to know about iOS 14.5

Check out all our Academy guides to complying with the disruptive iOS update

The release of iOS 14.5 on April 26, 2021 was highly disruptive for the mobile industry.

Apple introduced its App Tracking Transparency feature and the ability for users to decide whether they want to share their IDFA (identifier for advertisers) with developers, and therefore be tracked.

In May, the Post-IDFA Alliance released some early indicators about how the mobile ad market has been affected since Apple's requirement rolled out, with 21% more spending on ads in Google's Android after iOS required users to opt-in for ad tracking.

The Academy also explored the impact of this change for mobile game developers through a series of guest articles from experts, which you can now find gathered below.
