When Apple launched its latest software update, the company made a sweeping change to its web browser that accidentally shut out some legitimate advertising agencies. The Trade Desk is one of the innocent victims caught up in this aggressive privacy push. While the update aims to stop hidden tracking tactics, it ended up breaking standard ad delivery functions instead, leaving the ad industry with serious questions about fairness.
Update shuts down basic ad delivery for The Trade Desk
The problem surfaced right after the launch of iOS 27. Advertising journal AdExchanger reported that The Trade Desk could no longer serve ads through the browser. Apple appears to be targeting data brokers who sell user profiles. However, the block mistakenly hit the domain The Trade Desk uses to simply request and deliver ads.
The Trade Desk filed a bug report pointing out the error. The company explained that its real-time bidding system does not track individuals. It just bids on ad space as a page loads. Curiously, logs show that Google did not face this same hurdle and its bids went through normally. Since WebKit powers all browsers on the platform, this block shuts these vendors out of Chrome as well as Safari.

Beta versions show a fix is coming in the future
Apple is using a dynamic block list to manage these privacy features. This setup means the company can block or unblock advertisers on the fly. However, The Trade Desk remains blocked for now. The situation is slowly getting resolved in current testing versions, but the ad vendor has to wait until the final version ships to the public.
The company is actively building its own ad business while simultaneously cutting off competitors. As the brand pushes users to install newer software updates, the advertising industry is keeping a close watch. The longer these accidental blocks stay in place, the more antitrust questions the company will have to answer.
