The device maker’s upcoming iOS 14 will require that users opt in to allow its Identifier for Advertisers tracking feature to operate in individual apps. In a blog post, Facebook said the new system will affect its Audience Network service, which third-party developers use to sell targeted and measurable ads within their apps. The company said it is modifying its software accordingly. (Axios)

Talking point: Facebook CFO called the iOS changes “a challenging headwind” for the company’s fourth-quarter financial results on a late-July earnings call. But Wednesday’s post framed the move as more of a concern for developers and advertisers, citing the impact on “businesses’ ability to market themselves and monetize through ads.” That follows Facebook’s claim earlier this month that small firms using its new paid online events feature would receive only 70 per cent of the value of tickets bought on iOS devices because Apple refused to waive its 30 per cent cut of App Store transactions.
