Sometimes advertisers use a combination of user segments to target their ads. For example target audiences who read about baby products and financial products to upgrade their car.
To my understanding, in the current proposal each IG is examined separately, without dependency with other IGs, so targeting would be a lot less accurate.
I see that all IGs are sent to the trusted server together, but I don't think that the intention is to look at them together, but to save network calls (maybe I'm wrong).

Is there a solution for that?
