Issue setting up Mobile tracking

Hi, I am having trouble getting the tracking working with Android.

It’s working fine with web, and I can see page views and events come through in real time on the dashboard.

However on my android mobile app nothing is coming through.

I’m using the react-native-matomo library, tracking screen view like so:
Matomo.trackScreen('', 'Virtual Offering')

Which calls the following native code:

For setup I do:
Matomo.initTracker('[](', 1);


"react-native-matomo": "^0.1.1",
"react-native": "0.59.10",

implementation 'org.matomo.sdk:tracker:4.0.1'

What am I doing wrong?
Does native events come through in real time?
