Highlighting of Recently Added Contacts
When a contact is added to a relationship map, it is highlighted in green for 24 hours - as indicated in the example below.
Note: 24 hours is the default time-frame, your administrator can update this value for your org's relationship maps.
Highlighting is controlled by the Recently Added toggle. The toggle is enabled by default - as shown in the example below.
To turn off the highlighting of recently added contacts, disable the toggle.
