Data Activator is lagging behind by an hour

I have encountered an issue with the data activator recently.
For reference, I have created an alert from my Power BI report. My semantic model is in Direct Lake mode.

At 6:30 PM, my Power BI report displayed the latest data accurately. However, when I checked Data Activator, it was still showing data from 6:00 AM. My window and step size are both set to 10 minutes, so I expected it to update continuously. Surprisingly, at 7:00 PM, Data Activator suddenly processed and plotted values for the entire hour between 6:00 PM and 7:00 PM. Then, it stopped again and only updated the backlog at 8:00 PM.

Hi @ShravaniMuthe2 ,
Based on your description that Data Activator was delayed by an hour before it started sending out updates, after our testing we found that Data Activator may need to be refreshed after the data model is refreshed in order to detect changes in the data. Based on our search of previous posts, some users have also reported that Data Activator only recognizes changes in data after manually refreshing the Direct Lake data model.

Hi @v-xingshen-msft,
If the data activator updates and sends alerts after a data refresh then how will the alerts be sent in real time. My window size is 10 mins and i want the alerts to be sent as soon as the threshold is met. If it updates after an hour, it will send alerts after an hour which will not be real time.
