Touch id unable to activate but can't turn off
My iPad air touch id sensor button had just been cracked so I understand it doesn't work but I can't download any new apps as it's says payment failed due to not being able to read my fingerprint. The passcode option doesn't not pop up. When I go into setting to turn off touch id (as I've read about doing) there is not touch id and passcodes button at all? I've watched videos and my iPad is no longer showing Touch id with a red icon!? How can I turn this off?
