Limitations

The following limitations apply to the Measurement Protocol for Google Analytics 4:

  • Google Analytics change history does not reflect all API secret activities.
  • Conversion export to Google Ads is not always complete.
  • Conversion attribution in Google Analytics sometimes innaccurately shows (not set).
  • user_id requires both client-side and Measurement Protocol events to include the user_id.

These limitations will be addressed before a general availability launch.
