Now I wonder how come an "unlock app" paywall with that amount of money goes through the Apple review process unquestioned

Or for some reason if it's a Chinese app Apple will just not bother?

Or perhaps the app worked entirely differently during review?

Apple takes extra steps for that not to happen, and even then in this case it should suspend the app

It’s extremely difficult for Apple to stop apps from behaving differently during review than they do when downloaded from the App Store. A large number of developers implement schemes like this, and most aren’t scammers.

Even if Apple has reviewers download the approved app from the store to double check it hadn’t changed behavior, they can be gamed. Remember the Uber App Review geofencing that went on for years?
