AUTH121: Signed in as wrong user
What this means
The signed-in store account does not match the cashier on this till.
Each cashier keeps their own till data, so working under another account can misfile orders. Sign out, then sign in with the cashier's own account.
Your data
No order or product data is affected.
Troubleshoot
- The POS signs the session out on its own to protect each cashier's data — no order data is mixed between accounts.
- Sign back in with the cashier's own account; working under another account can misfile orders.
- If tills are shared between cashiers, make switching accounts part of the handover routine.
