I know for a fact at least 5 people have rated my course 5 stars over the past week or so, yet I've waited for days and the star rating in the search menus are not showing (stars are there but all are blank as if it hasn't been rated). Interestingly, if you click on the course to open a round, the course shows 5 red stars. So this seems to be an issue in the search menus only, and quite a big one if you're expecting people to search for high rated courses.
Just to add, my previous courses from last month show the star rating in search menu, so maybe this is a new issue? Any response would be great.
