n Stadia's store I can't compare some games for example red dead redemption 2, hitman 2 because they don't appear in the list of games in the store or when I search for all games they don't appear in the list how can I solve this problem?Hm you should be able to see the list of all games here. As far as I can see, Hitman and Red Dead Redemption 2 are there as well, so you can click on them and check them out.
If this is not what you meant, can you describe the issue a bit further or sent us a screenshot showing the problem?
