A widget can lag because iOS schedules refreshes or because its selected reminder was changed, trashed, or deleted.
Checks to make
- Open diReminder and verify the source item.
- Wait briefly after saving it.
- Edit the widget and reselect the intended countdown.
- Remove and add the widget again if necessary.
- Restart the device if multiple widgets are affected.
What the result tells you
- A widget is not an independent copy of the reminder.
- Low Power Mode and system resource scheduling can reduce refresh frequency.
Before trying again
- Keep the app and iOS current.
- Do not use the widget as the only time-critical alert.
