Can anybody confirm the details here? There is an API "Ad Click Attribution" coming to Safari, currently listed among the "experimental features" of Safari Technology Preview. From what I remember about it, and also just the name, this seems to be intended to soften the blow on advertisers here. This is Safari, not Apps, obviously, and I don't know this interacts wth in-app web views, or whatever methods they use to show ads.
