GA4 introduces warning for not set values but raises concerns over data accuracy
24 days ago
GA4 now warns about (not set) values, displaying an exclamation icon and a tooltip stating that changes may take 24 to 48 hours to reflect in reports. While intended to improve attribution data, this warning often creates confusion and false expectations. A frequent cause of (not set) is the tool itself, indicating that issues should be resolved before warnings are issued. This highlights ongoing problems with GA4 sessions, leaving users awaiting a real solution.
