What does Dispute mean?

When a payment order enters the “Dispute” state, it means that such payment order had previously been notified as finalised but it has returned to a pending state. The payment should no longer be considered confirmed and you should wait some more time before it can be considered finalised. Waiting times can vary based on the POS settings and the Bitcoin network activity. Unfortunately, although such events are quite rare, they can happen for reasons that depend only on the Bitcoin network and are not under under ChainsidePay’s control.
