Grafana Managed Alerts: No Instances

Grafana 9.5.3 Enterprise - Configured Alert Rule (multi-dimensional) with condition A/B/C, Preview shows alerts.
After Save&Exit there are no instances built.

Doing the same on v9.4.7 works a s expected.

Any ideas why - where to find logs?

hi @aescrob1

try increasing the verbosity of the Grafana server logs to debug and note any errors. More info on troubleshooting Grafana issues here Troubleshooting | Grafana documentation
