The upcoming changes to iOS 14, Apple's latest mobile operating system, making more difficult for advertisers to track customers, has raised concerns of the advertising industry, including Facebook. According to the Washington Post, Facebook told its investors that this privacy change would limit personalized targeting. According to this update, customers will now be asked whether they would consent to give apps the permission to track them with unique identifiers ('ID for Advertisers'). CBS reports that in response to this development, Facebook has announced that 'it will no longer collect the identifier for advertisers on its own apps for iOS 14 devices'.
