Unfortunately, increased issues occur with not updating widgets since the introduction of iOS 17. A not updating/stuck widget can look like this:

Usually, deleting the widget, restarting your device and re-adding the widget should solve this issue.

If this doesn’t work, please try to add a smaller widget and check off one of your tasks in the small widget. This should trigger an update on all of your other widgets as well.

Alternatively, you can try to edit one of your current tasks on the widget and see if the widget is updating now.
