Apple's iOS 27 Blocks The Trade Desk Ads in Safari
AdExchanger reports the ad agency was cut off in Safari after the iOS 27 release, appearing to be an unintended effect of Apple's data-broker crackdown.
Apple's release of iOS 27 blocked at least one advertising agency from serving ads in the Safari browser, according to the advertising trade journal AdExchanger. The agency, The Trade Desk, was blocked in iOS 27 by Apple itself, AdExchanger reported, citing a legitimate advertising company that found it could no longer serve ads to Safari when the update shipped.
The blocking appears to be an unintended consequence of Apple's crackdown on data brokers, according to the report, which was published by appleinsider.com. The report did not specify when iOS 27 became available or how many agencies were affected.
Apple has not commented publicly on the matter, and the company has not said whether the block on The Trade Desk was intentional.
Background
Apple introduced App Tracking Transparency in 2021, requiring users to choose whether to allow ad companies to track them using identifiers. After a heavy initial impact, the rates of users allowing tracking have risen again, and advertisers have found alternative ways to learn about users, according to the background to the report.
