Active Alert not showing up in Notification Policy

What happened?
All of the Alerts i set won’t appear on any notification policy, not even the default policy. I’ve also try to remove all alert and follow the alerting documentation step by step.
Previously i was able to setup and run a demo alert that sends to Slack. that no longer works now. Can confirm all alert are firing and not flapping, and contact points are tested to work.
What did you expect to happen?
firing alert should show up in notification policy, but policy shows 0 active instance.
Did this work before?
It worked for the first demo alert i setup, which counts log from cloudwatch and sends alert to slack.

Environment (with versions):

  • Grafana version: Grafana Cloud
  • Operating system: mac
  • Browser: chrome
  • Datasource version(s) (prometheus, graphite, etc.): loki cloud, cloudwatch, prometheus cloud.
  • Plugins: none

Configuration information:
example alert:

For context, this is the policy screen, the child policy matches with one of the other alert that was active

We are encountering the same issue. The alerts (with label team=devsecops) appear as Firing, and the alert instance routing preview indicates that they should be delivered to my contact point:

However, the notification policy shows 0 instances:

The contact point itself functions correctly, as verified using the “Test contact point” feature.

We have the same issue, and notifications weren’t sent. I think this is a connected issue.

I would recommend opening support ticket. Also, check what’s on the page “Active Notifications” it should show the current situation with active alerts. Check if your rule has firing instances.
