When I click “Run Now” in the analysis , the anomaly detection runs on the data [ in the screenshot 3 dots ]
Once complete , click “Explore Anomalies” provides more information
Maybe publish the dashboard with anomaly schedule configured ( Adding an ML insight to detect outliers and key drivers - Amazon QuickSight ) and check if it shows any results ?
If not , I would recommend to open a support case. Here are the steps to open a support case so that we can help you further: Creating support cases and case management - AWS Support . If your company has an internal IT team, you might not have direct access to AWS Support and will need to raise an internal ticket to your IT team. They’ll open an AWS Support case on your behalf.
