Universal Analytics has a setting (toggle) to enable session unification. This allows for events fired prior to the user logging in to be associated with that user's session. (During log in the Custom User Id (uid) is provided to enable this.)
However, I am unable to find this feature on Google Analytics 4 (GA4). Is this feature enabled by default? Or is this no longer supported? I have read almost all GA4 documentation, but unfortunately it is still pretty limited at the time of writing this.
Thanks!
