Try these steps to fix the issue:
1. On a computer: Go to Dashboard → Settings → Device management → Device codes, find the KDS device, and click Reset to generate a new code.
2. On the KDS tablet: Force-close the Square KDS app, restart the device, reopen KDS, and sign in with the new code. Ensure the tablet is online and the app is updated.
