Improved subproperty filtering of automatically collected events

Google is enhancing automatically collected events from web data streams in Google Analytics 4 to address a filtering issue for some subproperties.

In the future, all automatically collected first_visit and session_start events from web data streams will include the same event parameters as the event parameters for the first client-triggered event in a session. This ensures that these automatically collected events will be appropriately filtered in or out of a subproperty, resulting in consistent and predictable reporting.

Users do not need to take any action to enable this improvement, as this launch will resolve the issue moving forward.
