Custom Domain setup question

I have followed the documentation to setup a Custom Domain, and the DNS is now configured. When I go to the Custom Domain in my browser the front page come up but any links on the page still point to, so we’re off the Custom Domain as soon as we go to a second page. Anyone know how to fix this for us?

Experienced the same when I set it up, have not found a global app setting for it either
