We are migrating to Opsgenie from another product and I have been testing in Opsgenie. One thing we'd like to do is auto close alerts that people may have forgotten to over time.
I have implemented an automatic closure policy for these alerts as a preliminary trial. However, it appears that none of the associated or responder alerts were closed through this approach. I would appreciate any guidance in identifying any overlooked elements in this process.

Edit:
The auto close policy above works inconsistently. It would auto close alerts from integrations like Datadog. Alerts from other integrations like the Opsgenie Alert API it does not auto close. Same kind of alerts are sent through and only 1 occurrence.
