It’s unfortunately not by default attached to a providers profile info (I’ve hosed to include mine inthe “about me”tab) but one way to find reviews is to Type the companions handle into the search bar onthe top right corner of the page and it will come up with any query which have been posted about/by the companion (including reviews). It isn’t optimal but that’s one way of doing it)

Hope that helps dear.
Have fun and happy hobbying XO
