2024/03/21 - DFengage Version 2.0.1
- The “Clear this value” option is now available for date and time fields as well as VAS fields. “Clear this value” only appears when a field is optional and does not appear when a field is required or essential.
- A bug was fixed where the app skipped hidden fields in an activity even when the user’s role permission allowed hidden fields.

- The Today screen has new section dividers for Overdue, Due Now, Upcoming, and Completed activities, providing a more comprehensive view of your activities for today.

- Exiting an activity will save your responses to your device, so you can continue the activity later from the Today screen.
