What problem does Ancestry Match List Sorting solve?
Ancestry Match List Sorting lets you choose whether your AncestryDNA match list opens with your newest matches first or your closest. Ancestry always opens it by closest relationship, so checking for new matches otherwise means changing the sort on every visit.
How does Ancestry Match List Sorting work?
The choice is a switch called Default DNA Match List Sorting in the AncestryDNA Tools section of the pop-up panel.
