Erased iPad still thinks it is linked to my apple id
I completely reset my iPad 3, and sent it to a person in another state, who wanted to use it.
She cannot proceed with using it because it says it is linked to my apple id. When I look at my device list, this device is NOT listed. Only my phone, current iPad 6, and my mac are listed. How does she proceed? I don't want to send her my apple id and password, and it's expensive for her to ship it back.
