    This sounds like a problem of data syncing between Google Tag Manager and Google Analytics 4. Ensure that the ‘userId’ is defined correctly in GA4 as well, not just in GTM. Sometimes, data you see in the debugger doesn’t reflect in GA4 reports because it might not be configured correctly in GA4. Double-check the configuration settings and maybe wait a little because GA4 sometimes takes a while to reflect this data.
