ErrorLoadingExtensionAndDefinition in Application Insight. Most services/blades down.

Question

All our Application Insight instances are not loading the following blades: Overview, Failures, Performance, Availability, Troubleshooting guides, Application map, Users, Sessions etc.

Live metrics works.

This appears systemic, yet Azure Heath is reporting no known issues. Is anyone else seeing this?

Each screen shows the following error.

Answer 1

Btw, I did a Ctrl + F5 reload of the browser page with Application Insights and now everything loads fine. Not sure if the page reload helped or it's just a coincidence with timing and Azure fixed it at the same time.

Answer 2

I have the same issue when trying to load any of the views/blades. The "Self-diagnostics" from the error page doesn't find any issues/errors. "Azure status" shows no issues either.
I don't know if Microsoft is aware of the issue. Anyone with Azure Support plan please create a support ticket to let them know there is issue.
