I can no longer view summary rules. When I click on Summary rules it shows an error "NOT FOUND"
Anybody noticed this lately? It was working pretty well before 5th of December.

Hello @Khanna, Keshav,
Thank you for posting your query on Microsoft Q&A.
Based on your description, it seems that you encounter a 404 Not Found error with "DynamicSummaries.ReactView" whenever you try to access "Summary Rules (Preview)" in a Microsoft Sentinel workspace.
After investigating this internally, I found that DynamicSummaries.ReactView was experiencing unavailability, which affected an unspecified number of clouds, regions, services, and subscriptions. This issue might have been the reason for the error you encountered. However, I can confirm that the incident has been resolved, and DynamicSummaries.ReactView is now healthy for the resource.
If you are still facing the same issue, please let me know so I can recheck with the engineering team regarding this behavior.
Thanks,
Raja Pothuraju.

Hello, this is working for me and I tried 3 regions - you may need to raise a support call if its been down for days
Hello @Khanna, Keshav,
Thank you for connecting with me offline and providing the necessary information to investigate this issue.
After consulting with the Product Group (PG) team, they identified that the issue was caused by a problem with the AAD user details. Specifically, the error occurred because our service was unable to retrieve the user ID from Entra.
The PG team has released a hotfix to address this issue and implemented improvements to ensure that such cases do not occur again in the future.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
