Please configure "Coming Soon Page" first!

Hi Heroes

I have installed a new Multisite instance from scratch and when I am logged into the backend I can see all pages but when I log out I see a message called
"Please configure "Coming Soon Page" first!"

Unfortunately, I can't see the drop-down to enter the multisite domain with the problem anymore but you can check the as access is granted. This message appears on all subsites.

Is that a new feature of a new version of Wordpress and where can I configure that?
