How do I use the Business Manager app to update a menu item's availability?

    You can now make changes to your Online Menu by tapping on the Menu Manager feature on the tablet. It will prompt you to enter the PIN which you can know by calling the Support helpline i.e, +1(866)-629-9646. You will be able to edit the description, activate/deactivate an item, and update the prices.
