The app lists a booking in the same order as the web

Open a booking in Shelf Companion halfway through a hand-over and the items you still have to collect are now at the top of the list, where you are looking. The ones already checked out sink to the bottom.

Until now the phone did the opposite: it listed the checked-out items first, so every item you handed over pushed the remaining work further down the screen. The web booking page has always ordered the list the other way round, and the two now agree. A kit is judged as one block and only sinks once every member of it is out, a quantity-tracked line stays on top while any of its booked units are still waiting, and items that tie break A→Z by name rather than by when they were created.

This was a server-side change, so there is nothing to install. Every phone with Shelf Companion already lists bookings this way, whatever version it is running.
