Open Return, Move and the stocktaking scan page once while online (the app remembers them). If the connection drops, the page collects every booking in a queue (bar at the bottom, even after restarting the app); as soon as the device is back online, they are booked in order and the server's messages are shown. If the session has expired in the meantime, the queue stays until the next sign-in. Tool sets with a parts checklist can only be returned online.
