Hello everyone,
I connected some of my VMs to Microsoft Sentinel to learn a bit about the solution, create analytics rules, Workbooks, etc.

But in the middle of me using Sentinel, functions started "migrating" to Defender portal. And sometimes they are visible in Sentinel, sometimes not, you only get "his page has been moved to the Defender portal for the optimal, unified SecOps experience. Click here to go to the Defender portal"

Is there some mapping of functions from Sentinel to Defender?

Like I am really missing the "Overview" tab where I could see the number of events, usage, incidents, etc.
It worked for my 5 minutes ago, but now it also moved to Defender.

Where would I find the equivalent of "Overview" in Defender?
Keep in mind, I have no Defender for endpoints, only Windows AMA connectors.
