React Native Facebook SDK IOS Event is Not getting fired on Event Manager

Question

I've got react-native-fbsdk-next installed on my project. It's properly installed.

import { AppEventsLogger } from 'react-native-fbsdk-next';

   facebookSDKInit = () => {
    FBSettings.setAdvertiserTrackingEnabled(true);
    FBSettings.initializeSDK();

    AppEventsLogger.setUserData({  //doesnt get registered
      email: '[email protected]',
      firstName: 'ishak',
      lastName: 'ertem',
    });

    AppEventsLogger.logPurchase(15, 'USD', { param: 'value' }); //gets registered
    AppEventsLogger.logEvent('Test', { //gets registered
      user: 'ishak',
      email: '[email protected]',
    });
  };

I call facebookSDKInit on componentDidMount. Events starts getting registered except when i call setUserData or setUserId, they dont get registered in the events manager.

Would appreciate any help here. Thanks!
