When an individual is signed in to your InVision V7 team and completes certain actions, the system time stamps the action and automatically updates the info in the Last Seen column on the Team tab of the People page.
Excluding guests, anyone on the team can access People page and see the Last seen column on the Team tab.
To check the date that an individual last took an action while signed in to your V7 team:
Sign in to your InVision team here: your-team-name.invisionapp.com
On the left, click People.
Under the People heading, click the Team tab and click the Search icon () or scroll through the list of users to find the person.
To the right of the person's name and role, view the info in the Last seen column.
