April 28, 2021 Apple has rolled out its iOS 14.5 software update this week for iPhone users, including a major change that could restrict the reach of small businesses’ paid Facebook ads. Following Apple’s announcement of a raft of new products at its annual Spring launch earlier this week, the tech giant said in a statement that the iOS 14.5 update would soon follow. As part of the update, users will receive a pop-up asking permission for Apple to track their activity across the internet — potentially blocking the collection of the very data that Facebook uses to target ads. So, how will it affect advertising?
