It’s awful. A lot of basic stuff is just missing.

I had an Xbox game pass trial. When it expired it closed the game I was playing. No message. When I tried to reopen the game nothing happened. None of my games worked. But most importantly, it never told me why. Nowhere in the interface does it communicate “your trial ended” or “hey resubscribe to game pass” or “you can’t play games anymore” instead everything just stops working with no explanation. I was midway through contacting support when I pieced together that maybe the trial ended, and confirmed that on their website. That information isn’t available in the desktop app.

(This was over a year ago, hopefully it’s fixed now?)
