Ancestry replaced the old Your DNA Home Page about 2 weeks ago with a new page that functions completely differently than the old one, so the extension needs to be updated to support the new page. Some have been able to access the old version of Your DNA Home Page and access the buttons that way.
I have been working on a new Your DNA Home Page in between all of the work, family and church activities these last couple weeks due to the Thanksgiving holiday. It almost works again, though I still need to set it up to detect when you select a new test kit from the drop down list. I also until a month ago, the matches had custom ids for each kit, which required scanning every match for ancestor data. However, they recently changed to use the unique test id for each match, so I want to rewrite the way the scanner works to only open each match once. This should make the scans go quicker and also make the database smaller.
