Access to new responses is not actually restricted

## Context

We have set an escalation path for overdue responses:

This is communicated publicly to clients in demos, support and guidance:
https://articles.alpha.canada.ca/forms-formulaires/monitoring-overdue-responses/

When signing in with overdue responses beyond 36 days, we have a message indicating that we restrict downloading new responses until the old ones are downloaded and signed off for removal. However this does not seem to be the case?
