Glad I'm not the only one.  No, my "new" card reader has never worked.  The goPayment app sees it as a nearby device but it never gets registered in the app and won't work.  Since it never registers in "my readers" in the app, I also can't update the reader as several techs have suggested.  Taking in person credit card payments was one of my primary reasons for switching to quickbooks.  It's rather frustrating.  No solutions so far.  I have the most recent version of goPayment.
