Due date change

So baby is due Nov 22. Based off of our 9 weeks scan which i was told will be the most accurate through out the pregnancy. At my scan yesterday baby measured 4 days ahead so they changed the due date to nov.18.

Baby will come when she is ready regardless of her due date lol but did you personally tell people the new date or leave it the same? Did you change your apps to reflect the due date? Lol
