After both the client and freelancer have left feedback for a closed contract, the feedback WILL SHOW UP on the freelancer's profile page. But not necessarliy immediately.
You can just wait.
The feedback will show up eventually. Usually within 24 hours.
But there is also a little trick that usually works: Make a tiny change to your profile overview text, and save the change. This should cause your entire profile page to refresh in Upwork's caching system, and thus display your latest feedback.
