Hello! I'm new on upwork but I already have few contract. I just finished one and client left a review for me but it's don't show up in my profile. Can you please tell me how it works? Do i need to add this review mannualy?
The reviews show up automatically.
You don't need to do anything.
But they don't show up INSTANTLY. Content on your profile page is cached (for speed optimization purposes.)
Just wait a few days and the new reviews will show up.
(Or if you don't want to wait, you can make a minor edit to your profile overview text and save the change. That forces Upwork to re-generate your whole page, and that will force the latest review onto your page.)
Upwork's feedback system is double-blinded; you won't see your clients' feedback unless you have already given him feedback or after 14 days. In case you left him feedback, then you don't need to do anything from your side [You can't add clients' review manually].
Be noted that feedbacks may take up to 24 hours to be updated and shown on your profile.
I hope this helps. Wish you the best of luck.
