How to remote erase wifi only ipad
I recently sold an wifi only 3rd gen ipad pro but forgot to reset it before I ship. Now the buyer is asking for my password to unlock it. I have remotely erased it in my iCloud and it says my ipad will be erased when it connects to the internet next time. But it must be already unlocked with a password for it to connect to the internet, isn't it? The remote erase seems pointless on a wifi only device if that is the case.
