Open the KDS manager page and review the device settings
Go to Kitchen Display Screens.
Find the screen in Registered KDS Devices and check that it is still active, named correctly, and tied to the right location.
Use a fast triage order for missing tickets, silent devices, scheduled orders, and screens that do not match each other.
When KDS acts wrong, start with the simple checks first instead of re-registering the device right away.
The fastest order is: confirm the device in Kitchen Display Screens, refresh KDS, test with a known-good order, then decide whether the screen needs a new setup code.
Quick facts
Go to Kitchen Display Screens.
Find the screen in Registered KDS Devices and check that it is still active, named correctly, and tied to the right location.
Open Kitchen Display Screens and compare the Sync across devices setting on both screens.
When sync is off, line-item completion and clears are saved only on that one device.
Use a new setup code only after the fast checks fail
Re-register the device when the token was revoked, the screen keeps opening the wrong queue, or refresh and test orders still do not recover it.
Generate a fresh code in Kitchen Display Screens, open KDS Setup, and register the screen again with a clear nickname.
