are you saying that the app opens up a webview in the default browser, computes the fingerprint, then sends that info back to the server, which compares it to recent link clicks, possibly also taking into account other info like ip?

Yes. That is what I am guessing. If the app is opened close to the user's click, it might be fairly reliable. I think hasOffers and few of the other tracking companies do this. But I am sure branch has figured out a better way to fingerprint.

I thought the IDFA could be used to do tracking like this, or am I misunderstanding something?

The IDFA has been blessed for this. All of our partners have been submitting their apps with that option checked without issue.
