Pre-Install Useless and Buggy for Xbox (Beta) App for Windows 10?

Hey guys, I am posting here to see if anyone has similar issues, and if so to possibly raise awareness of a pretty irritating bug in the Win10 Xbox App.

Pre-installing games before release is broken. I have pre-installed Wasteland: Remastered and Ori and the Will of the Wisps both, and had similar issues with both that ended in wasted time and frustration.

Essentially, if you find the game on Game Pass and pre install it, the app will download... something, equivalent to the size of the game to release. After that, you wait until release day and once you go to play, guess what, the Play button will turn into
an Update/Pause button after you click it, and the app will download an "Update" with a size equivalent to the entire game.

For Wasteland I went through the process of reodownloading it, only for the game to stall out and stop loading completely after a few seconds (noted in task manager of the RAM allocation not going up). I had to install that game a third time to
finally play it. At least that one was small.

With Ori and the Will of the Wisps, it took up 15gb of space, and my drive was near empty with it and some other installs. I got back from a trip, hype to play it, only to find that when I hit play I got a box that told me it needed to be updated, before
the program closed out. The update is the size of the entire game, 15.1gb! To top it off, since that drive was full and since you cannot find out what game is installed where due to the coding and encryption (probably the wrong words) of the game install files,
I couldn't even uninstall the right games to make space for it. I uninstalled 3 games before I had enough space, and it was like playing Russian Roulette because I had no idea what drive I had installed them on. So now, I have to reinstall those games on top
of Ori.

So, essentially the take away/suggestions I'd like Xbox to note for Game Pass on Windows 10:

1. PLEASE give us a way to easily locate what drive games are installed on. With Steam and Epic I can actually read and find games manually if I need to uninstall them per drive. This feature is something you would think would be baked in, but its not (or
impossible to locate) and I don't understand why.

2. Fix pre installing or disable it. Maybe I got unlucky with 2 games, but what is the point of pre installing if, you know, it doesn't actually pre install the game for immediate play on release?

3. A combination of the two above: The main culpriate to my frustrations was that the pre installed 15gb of Ori was considered to take up 15gb of space on my drive, thus making the 15gb "update" impossible to perform without uninstalling other games. Please
fix this!

PS, my windows is up to date, and I am on a Preview/Insider build of Win10.

Thank you for your time, I love game pass but this Launcher is in serious need of some work.
