Is it possible to get install attribution for Apple Search Ads / Google Play Ad working without ejecting?

We are on Expo 36. We’ve tried everything we can to get ad attribution working for installs - we’ve attempted using Branch by itself, Segment -> Branch, and Segment -> Kochava.

I’ve found this post from July: Mobile Measuring Partners (MMP) and Managed Expo where it looks like as of 6 months ago, there was desire for this functionality but no support yet.

I’m aware of the react-native-apple-ads-attribution package, but I want to see if we’ve exhausted all options before ejecting to use it.

Any help would be extremely appreciated.
