Hello,
Here are a few possible reasons and solutions:
Time Zone Settings: Double-check that the alert's time zone settings match your intended 9 am JST schedule.
System Time: Ensure your system's clock is synchronized and accurate, as discrepancies can affect scheduled tasks.
Configuration: Verify that the alert's configuration hasn't been altered and is set to run daily at 9 am JST.
Logs: Check the logs for any errors or warnings that might indicate why the alert didn't run as expected.
Permissions: Make sure the alert has the necessary permissions to execute at the scheduled time.
