I have set up a ga4 tag in a GTM ss container, through Stape. All works fine and I collect a lot more data. However, a lot of this new data is put under Unassigned in GA4. Within this traffic source the session with engagement are also really low. It looks like the original traffic source is not passed through to GA4. How can we fix this? Which setting am I missing? And can we also make sure that session with engagement are measured properly?
This is how the containers are set up:
just used the server url in the transport url in the GA4 tag
server side container:
Hope that someone can help out.
