Firebase Analytics & Attribution

Does anyone have any way to shed some light on a problem I have with Firebase Analytics not reporting attribution data back to Analytics

I initialise Firebase right away in the app.component.js

  initializeApp() {
    this.platform.ready().then(() => {

        enabled: true,

I can see lots of output in the xcode debugger when this triggers too

[Firebase/Analytics][I-ACS023007] Analytics v.8.4.0 started
[Firebase/Analytics][I-ACS025036] App Delegate Proxy is disabled
[Firebase/Analytics][I-ACS800023] No pending snapshot to activate. SDK name: app_measurement
[Firebase/Analytics][I-ACS023012] Analytics collection enabled
[Firebase/Analytics][I-ACS023220] Analytics screen reporting is enabled.

and i can trigger events etc without issue.

What i’m looking for is for the campaign data to be sent over to analytics when the app starts off, but I see only (not set) where is should be related to the campaign.

This has been the way for many versions of both cordova and capacitor firebase / google analytics.

If anyone can point me in the direction of what im missing here.
