I think the store and the library search sucks on EGS. You can’t even tell what games you have purchased and for what platform (pc/ios/android). Best you have is the purchase history on their website and app.

I use Heroic Launcher (on Arch btw and Bazzite for kids) and that luckily works really well for displaying games that you have bought on PC. But there’s no such alternative for iOS or Android, and even Heroic doesn’t show you what games there are in your library for mobile.

I think the real atrocity is the inability to properly search on titles that you actually purchased, free or not. At least on Linux I have Heroic to list all games. But on IOS and Android you have to wade through shit or go based on your purchase history to find the titles among the free with in-app purchase shit.
