I just today learned of this tool. I have clicked the button to add it. Then when I went to my dna home page and clicked the little icon, it gave me a message "If you have not done so already, go to Your DNA Home Page and click on the "Full Scan" button near the top of the page to scan all of your match data." I went to my home page and searched everywhere and can not find a full scan button. Help please? Thanks!
