Passcode changed by itself
I was using my iPad Air 2 this morning and it ran out of power.
I plugged it in. After an hour I went to use it and it requests 6 digit pin. Fails. I'm now locked out for 15 minutes.
I use the same PIN on my iPhone and iPad and I can unlock my iPhone so I'm not loosing my mind. What is the easiest way to access my iPad?
Should have the latest IOS on it.
Thanks,
Mark
