Hello, my wife uses her iPad for her Square Restaurant app. She decided to buy a new iPad to use just for this app. I mistakenly setup the new iPad as if it was replacing the current one, so now it is basically a clone of the personal one. I want to factory reset it, but I am getting an error. I am going to settings/general. I then select "Transfer or Reset iPad". I then select "Erase All Content and Settings". The "Erase This iPad" screen comes up. When I select Continue and put in the passcode, it comes up with "An Unknown Error Occurred, Please Try Again Later"
