I'm curious how they would handle this with regards to lift tests. You can ask Facebook to not show your ads to faction of the addressable audience, and then calculate sales for the treated and control groups. If they don't make the randomization binding across platforms, it can several reduce the incrementality measurement (effectiveness of Facebook ads).

That way the experiment and control groups will be consistent across the apps, with the downside that a user changing their email might migrate between groups. But changing your email has to be a very rare operation.
