Hi there, I can't seem to find another way to raise this. I bought a used hub from ebay, and I am trying to register it. Unfortunately, it is already registered and I cannot get a response from the previous owner. Is there any other action I can take?
Previous owner should have de-registered it before selling just like with any internet connected device these days. I would run that up the flag at eBay and give the seller a negative rating.
But, in spite of that @support_team can probably get it squared away for you.
