I've set up an SLA to measure time since a Support Engineer last contacted a customer. (For the purposes of development, I've specified 1 hour on Priority 1 issues and 4 hours on other issues.) See below:
I tested by leaving a non-priority-1 issue uncommented for 4 hours. The SLA breach was triggered.
The SLA breach was NOT reset when I posted a customer-facing comment in the portal. However, the SLA breach WAS reset when the customer added a comment to the issue.
Am I making an obvious error here?
