Reply To: Why are all my GA4 events being categorized as unassigned in channel grouping and (not set) in source/medium?

This issue could be due to something as simple as a tracking code implemented the wrong way or more complex like an issue with how the website handles referrals. You can try a few things like checking if the tracking code’s installed correctly or if there are any redirects that might be wiping out the source information. Also, check your filters and settings as a wrong configuration could lead to ‘unassigned’ traffic in GA4. It’s trial and error, but one of these should help solve the problem.
