Not all the appointments (past and future) appear in my clients' dashboard in the Coaching Activity History. Why is that?

In order to keep the client dashboard page light and easy to load in the browser, there is a limit of 50 items displayed in the client dashboard when it comes to all items pertaining to the coaching activity history: appointments, invoices, completed forms, etc. The system comprises in that number limit the most recent activity and that is why a client with a longer and richer coaching activity will not see everything that happened.
