In Visitor profiles and Visits Log, as well as the Live APIs, by default Matomo will show the first 500 interactions in each visit, and may then display the message “more pages by this visitor are not displayed”. All interactions are tracked for all visits, but the UI doesn’t display the interactions by default to keep the reports fast.

You can configure Matomo to display more pages in Visitor Profiles and Visits log by updating the config/config.ini.php and setting the following INI setting under the [General] section, for example to show up to 1000 actions per visit:

 [General]
 visitor_log_maximum_actions_per_visit = 1000
