I have a used iPad and the setting have been reset but when I try and set it up I get this message: This iPad is currently linked to an Apple ID. Sign in with the Apple ID that was used to set up the IPad. I have tried to contact the seller but have yet to get a response. Had the iPad for a month now and can't even use it. Is there anyone that knows what I can do? Its one of the newer models. It has the newer charger with it.
