Currently when you go to an account, you can all see Open Actives on that account. It would be very helpful for people mainly using Dynamics 365 / CRM on iPads, to view both scheduled, open and completed activities.
Change view to all activities and then pin the view / or it should be the standard view.
The view showing all activities, should should be sorted, so that you see the newest first.
Reason: This will make it easier for the user to get an overview of the activities related to an account. As it is now, it is difficult to get an overview of the latest/newest activities related to an account.
