It's their largest issue and they literally just won't fix it.. Ostensibly because they don't "track user behavior". Yeah sure Epic, go with that.

When it introduced Steam Direct, Valve prioritized the development of Steam features that helped users discover games they might be interested in, such as the Discovery Queue. The Epic Games Store will continue to get interface updates, but as a matter of principle, Allison says that Epic will not track user behavior and use it to algorithmically recommend games. Epic has said in the past that it's more interested in supporting the game discovery that already happens outside of stores, such as on Twitch and YouTube.
