What happened to "check configuration"?

I am using configuration.yaml to manually configure Home Assistant. In previous versions there was a Check Configuration option under Configuration / Server Management. Now it’s gone. Where did it go?

It’s still there for me.

I am using version 2021.3.4, and it’s not there for me.

I see… Do you have ‘advanced mode’ enabled in your user settings?

That was the missing part, thank you.
