What is it supposed to do?

This is probably something new, but I don’t know what it should do, because it takes me to the page in user mode even though I am logged in as admin.

Is this a bug or some feature I don’t understand?

You are already logged in.
You might consider clicking on the “Back to home page” button.

I know that, but it takes me to the user’s page (regular one without access) - which is a bit weird
