"Last Active" Date

The "Last Active" date records the last time that a user logged into their Ambition account.

The Last Active date is measured through Google Analytics, which is Javascript-based system.

Ad-blockers typically block Javascript-based programs, which can then skew the data which Google Analytics collects. 

Additionally, due to Google Analytics using first-party cookies to collect data, page views, sessions, and time in Ambition, Google Analytics data will not be collected when viewing Ambition within Salesforce.

If your users use ad-blockers or access Ambition primarily through Salesforce, it's possible that log in attempts are not being recorded in Ambition, which can make it appear as if a user had not logged in for a long period of time.
