Google Ad Conversions from Firebase events stopped working with Expo app launch

We have a React Native app that uses Firebase events. Firebase is connected to Google Analytics and Google Ads. Everything was working - Firebase events would flow to Analytics and Ads and Ads properly would track conversions.

We recently changed our app to use Expo and now the events are going to Firebase and flowing to Analytics.

But Ads has stopped receiving the events it seems and we have no idea why - the conversion says “No recent conversions” since January 24 :frowning:

Really need help - google-services.json is included and we know Firebase is getting the events and we see them in Analytics. But something has stopped the conversions in Ads.

Ideas…?
