Symptoms

The POS shows offline mode, sales stay pending or 'processing' after reconnecting, or sales you took offline are missing from reports.

Why it happens

• Device still offline or on poor Wi-Fi
• App signed out, deleted or reset with pending payments
• Offline payments not reconnected in time (expire if not uploaded; Square's article cites 24-72 hours)
• Square disruption
• Some offline payments are declined when finally processed
