I'm sorry about the issue. Please make sure you have rebooted the iPad this way: Press and hold both the Power (On / Off) button and the Home button (which is located right below the screen) together for at least 10 seconds, until the Apple logo appears, then wait a bit, then check.
- If that does not work, please open Settings app icon, then tap on General option on the left, turn off option Gestures (or Multitasking / gestures) on the right, then turn that option back on and check.
Please reply at the box below to continue. Thank you.
