Facebook Says Apple’s New iPhone Update Will Disrupt Online Advertising

Facebook says privacy changes that Apple has made to its newest operating system will cripple Facebook’s ability to serve targeted ads to iPhone users while they use outside apps. The announcement, which Facebook made in a note to app developers, will affect its Audience Network business, which connects users’ Facebook identities with their off-platform activities. That enables the company to serve them ads on apps outside of Facebook’s. The changes go into effect with Apple’s new operating system for iPhone, called iOS14, which was released in beta form to developers recently.
