we upgraded from v8.2.5 to v9.4 and kept the legacy alerts.
Since then it is not possible to save new alerts. Configuration and “Test rule” works as usual but after saving (panel + dashboard) it won’t show up in the alert list.
The old alert rules (created in v8.x) are still available and working (edit, pause, notification).
Can this be caused by changes in the ini? It would be great if there is a solution in which keeping legacy alerts is possible.
