Staying signed in

Staff sign-in has a Keep me signed in on this device box. Leave it ticked and the session persists between visits as normal. Untick it and the session is held only until the app is fully closed, which suits a shared or borrowed device. Customers are always kept signed in on their own phone, so the box is shown only for staff. This is separate from the app lock, which can end the session on a timer even when you are kept signed in.
