I shelled out my dollar for a month of Flight Simulator. The Windows Xbox app is such dogshit, why does Microsoft always try to do Microsoft things instead of just making something that works?
To start with, apparently you can only install Game Pass games through the "Game Pass" tab of the app - like if you just look up a game (I tried this with other games) that's included in Game Pass and open its page, and it even says "included with game pass" there, you can't actually install/play it from there, because you're looking at its
Store page, not its
Game Pass page.
And can you
search for stuff within the Game Pass tab? lol, no, that would make way too much sense, try finding it by category or scrolling through a list of every game alphabetically.
So, okay, finally found Flight Simulator through the Game Pass tab (after seeing elsewhere that it apparently released 2 hours ago). Can I install it?
Nope. Note the "releases 8/17/2020" on the bottom left. But it's "not available at this time".
