If you would like to get back previously rejected Record Matches, you can do the following:
Use the filtering option for Record Matches. Click here, if you need further instructions and details about the filtering feature.
Start by changing the filter to show only rejected matches and reduce the number of stars to zero.
Click on the 'Review matches' button to view the matches you have rejected.
Note: you can view rejected matches sorted either by collections or by people.
You can use the “x” (Reject Button) under the match to undo the “reject” status.
