This is annoying. We don't want 2 invoices for one job and we don't want to delete payments or invoices. We don't want to tell customers to switch browsers or go incognito, which doesn't work anyway. Just make it seamless for us to receive payments.
We especially don't want customers erroneously told their invoice is paid when it is clearly not. It not only won't let the customer pay, it tells them the invoice is paid. Please fix this.
