I would keep a record of the appeal submission and the result. This will be useful as sometimes you are asked if you were ever denied a visa and you can provide this evidence that you were denied, but the rejection was reversed on appeal.
Practically though, it looks like the premise for your application is no longer valid. You have already visited the Schengen area.
Your visa (even if issued) would be invalid as your travel dates would have passed.
