Your subscription status changes to FROZEN if you have an overdue invoice that exceeds the 5 days grace period. In the FROZEN status, access to the respond.io platform will be blocked until you settle all your overdue invoices. Although incoming messages will still be received and stored in this status, Workflows cannot be triggered and outgoing messages cannot be sent. If the overdue invoice is not paid by the end of your billing cycle, your subscription will be canceled.
