Currently, the Tasks list in mobile does not automatically refresh when the user is viewing the page. This was done so that users would not have to constantly re-sort their work when managing their day.
To get the Tasks list to refresh, users must navigate between any other screen and back to the Tasks list. I.e. navigate to the Notifications or Settings tab, then back to the Tasks list. The application will refresh the list of Tasks provided that there is a working internet connection.
Based on feedback from Clients, we are adding the ability for a user to "pull to refresh" the list view. Once implemented, users will be able to "pull" their list of tasks by swiping down the page, and the tasks will refresh. This enhancement should be available as part of an August update. We will update this notification once the release has been completed.
