Does any released game use UMG for their menus?

I’m just curious, because all answers I’ve been able to find online regarding disabling mouse input and implementing gamepad support seems hacky as hell…

…so are all released Unreal game menus made in either C++ or Slate?

Because my working theory right now is that UMG isn’t a production ready solution for indie developers to make their game menus in.

Is it just a documentation problem and a wildfire of misinformation on top of all search results, or are there any devs here with shipped games who managed to figure out a complete UMG solution the way Epic intended?
