Ad blocking is malfunctioning in iOS 10.3 beta. (With video)

There are no issues from iOS 9.0 through iOS 10.2.

However, there is a problem with iOS 10.3 beta.

Problem: A blank space is placed where the ad was removed.


I attached the test video. Please watch with subtitles.

I have found the exact cause of the problem.

The css selector below does not work.



[id='ads'] or [class='ads']



However, the following css selectors work normally.



#ads or .ads
