Facebook’s ability to track users and show them certain ads appears to be tanking thanks to Apple’s “ask not to track” feature, according to some advertisers.

Apple rolled out the privacy prompt in late April with iOS 14. 5. Since then, nearly half of all iOS devices worldwide have at least version 14. 5 installed, according to Statcounter , and a vast majority of these devices’ users possess chosen to deny Facebook and other apps the ability to track them. Nearly three months after the feature’s launch, just 17 percent of users worldwide have got opted in, according to analytics company Flurry .

The changes could have a significant effect on Facebook’s bottom line. Eric Seufert, an analyst who writes Mobile Dev Memo, forecasts that if only 20 percent of users consent to tracking, Facebook’s revenue could drop 7 percent in the first full quarter that the particular opt-in prompt is active (the forthcoming third quarter). The company} warned back in February that the iOS changes would curtail its ability to track customers across the Internet.
