The kiosk is deliberately locked to the ordering screen so a customer can't reach anything else. There are two ways out, and both are meant for staff.

The hidden menu

  1. From the language selection screen, tap the top-right corner once, then the bottom-right corner three times in sequence.
  2. Enter your admin password and tap Confirm.
  3. In the settings menu, select Close the App at the bottom left.
  4. Confirm on the popup.

You need the admin password. If you don't have it, whoever holds admin access on your account does.

Restart instead

Restart the kiosk. When it boots to the settings screen, tap Close the App.

Use this if the password isn't to hand.
