Microsoft is pretty much the king of wonky apps whether it's their inconsistent and poorly designed OS or their own apps. It does not surprise me at all.
Don't take me wrong, they do make a lot of good stuff (mostly on the developer side) but their end user facing stuff is at best inconvenient, at worst a pile of crap.
This. As someone who is forced to use their entire suite of products at work (desktop and apps), I'm continually amazed at how awful the UX/UI is. I once wrote the head of IT at my job an essay about how awful Planner is and how his decision to force the company to use it over Trello was a disaster. It's almost as if the product team at MS doesn't actually use the products they develop. A lot of problems that are clearly evident by just examining basic user flows are either ignored or missed. I don't use GamePass on the PC but I'm not surprised by any of this.
