Hi guys,
I'm testing the new GA4 and most of the times it's not tracking correctly, showing (none) instead of the UTM values, although I'm sure I'm passing the 3 UTM paramaters (source, medium and campaign) correctly from my traffic sources as they all appear in

Any idea what the issue might be?
Thanks in advance!
It seems you're not the only one - https://support.google.com/analytics...80951242?hl=en
I tested and on one of my GA properties that I converted to V4 I get the same issue, where in the real-time section I don't see source/medium when I am very clearly passing them in the URL.
But if I check the acqusition data, I can clearly see medium/source/campaign info from links that I'm using... so they are working to some extent.
I used a Chrome debugger plugin that supports GA v4 and noticed in the events set there is nothing about utm params, so it must parse the URLs to get this -- which would only work for the initial entry, as later pages won't have these.
I tried forcing these via GTM and I still don't see them in real-time, though I can clearly see the raw events with custom params, so its a bit of a mystery. As a backup I would use GTM to push these events, potentially as separate parameters so if they aren't tracked as "Campaign" you can still see them under events > property > campaign (or whatever you name it).
