SKAdNetwork: Is it 'last click' or 'first launch' attribution?

Since same app can be advertised by multiple adnetworks, consider this scenario. Youtube shows Ad, user invokes in-app store sheet and install the app but does not launch it.
User sees Ad for same app in Instagram, invokes in-app store sheet. Since it is installed it will show open. User click on open and it launches the app. Whether Youtube or Google receive postback in this case?
Would really appreciate an answer here.

Does SKAdNetwork employ last click attribution…i.e. will the ad network still receive credit for an install if:
  • A user clicks on an ad and it launches the install dialog

  • The user decides not to install

  • At a later time, the user returns to the App Store and downloads the app

Thank you
Did anyone find the answer to this question?
