The Seasonal Goals widget displays the top goal in the ‘My Goals’ tab, which will always be for the current season. In order to get another goal in the current season to show up on your widget:

  1. Go to your home screen.
  2. Tap and hold until it starts wiggling and you enter edit mode.
  3. Tap on the Seasonal Goals widget, it should bring up an option to “Choose” a goal.
  4. Select the goal you would like to show up.

Now, that goal should remain on your widget.
