Orders with no location
The board shows work for the locations your account is allowed to see. Orders that carried no location at all could be hidden from every account with a location list. The board now treats an unlocated order as belonging to your default location, which is your only active location, or the one marked as default. A location outside your list is still hidden on purpose.
What to do. Reload the board. If you run more than one location, check that your account has the right ones, and that one is marked as default. In Backoffice, open Settings, Locations, edit the location and tick Default location. The app shows the default but cannot set it.
Tickets that never leave Incoming
If old tickets sit in Incoming after the guest has paid, the board was not told the bill was settled. Paying a check now moves its kitchen tickets to served, and they leave the board after the retention window (about four hours). Tickets that were already stuck before the fix are not moved for you.
A ticket that will not go to ready
If marking a ticket ready fails with a conflict, the ticket was probably already in preparation through another view. The kitchen board and the order screen kept separate records of the same status and disagreed. They now agree, in either order. Reload the board and try again. A ticket that was flagged as failing before the fix may still show "The board change was saved, but its source update needs attention before another action." Write to support, because there is no retry button yet.
Voided sales
When you void a sale, its open kitchen items are now cancelled too, so the kitchen does not cook a dish nobody will pay for.
