Alert Not Receved

Hi Expert,

Can you please advice what could be reason if the Alerts are not received some time as per set frequency.

I have tried with Simple Query of PO Pending report but alerts are not received some time.

For more detail refer attached screenshot.

As per screenshot First Email I have received 13 Jan 2022, 03:26 & Second is 13 Jan 2022, 08:27 after 5 hours which is my alert frequency.

Now 3rd time I have not received email after 5 hours, it's received on 13 Jan 2022, 18:26 instead of 13 Jan 2022, 13:26
