Why did my AncestryDNA results Change 2020?

AncestryDNA calculates your ethnicity estimate by comparing your DNA to a reference panel made up of DNA samples from more than 55,000 people, representing 77 groups. Because our reference panel and the way we analyze your DNA both change as we get more data, your ethnicity results can change as we get more data, too.

Why did my ancestry change on 23 and Me?
