Facebook is warning developers that privacy changes in an upcoming iOS update will severely curtail its ability to track users' activity across the entire Internet and app ecosystem and prevent the social media platform from serving targeted ads to users inside other, non-Facebook apps on iPhones.
The changes requiring users to opt in make the IDFA essentially useless, Facebook warned developers today. Facebook apps on iOS 14—which includes Facebook, WhatsApp, Instagram, Messenger, and a host of others—will no longer collect users' IDFA.
"Despite our best efforts, [the changes] may render Audience Network so ineffective on iOS 14 that it may not make sense to offer it on iOS 14 in the future," Facebook further explained in a blog post. "Our ability to deliver targeted ads on iOS 14 will be limited... as a result, some iOS 14 users may not see any ads from Audience Network, while others may still see ads from us, but they'll be less relevant."
