Thank you Daryn.
As was already written by some of the other users, the fact that there are no operating hours prevents this from being effective. If our service desk is open from 9 AM - 5 PM, we get a ticket at 6 PM, and our escalation rules are set to run after four hours, the ticket should not escalate 10 PM, but rather at 1 PM the next day.
Please let me know if there’s a workaround for this.
