I can't see ratings of all games on my wishlist. They simply have 5 blank stars as if they were "awaiting more ratings". But on their respective store pages average ratings are already present.

I'm attaching an example. Alien has average rating of 4.5, Amnesia - 3.4, while Arise still doesn't have enough ratings. Meanwhile they all have blank stars on wishlist. And if I sort wishlist by user reviews, all games with blank stars appear at the end, so this is not purely visual issue. Re-adding a game to wishlist doesn't change anything. I can't pinpoint any reason why it only affects specific games.

This has been noted on the forum before, typically by people who notice Cyberpunk 2077 has a 5-star rating in their wishlist but 3.7 on the store page, and immediately conclude it's intentional deception.

I reported the issue on March 25, 2021 in support ticket 1000944. I'd opened it because filters in the wishlist didn't work properly, and ended up discovering more problems, including this one.
