I own the Xbox Ultimate Game Pass and I have downloaded the tech test on my Xbox, but I cannot download it on PC. I cannot find it under the Game Pass section of the Microsoft store either.
Are you on latest windows 10 update?
I believe it’s 1903…
Since you have the Game Pass, you may need to use the new Xbox App to find it under the Game Pass, not the Windows Store.
You have to be on the latest version of Windows if you want to download the app. Here is a link to download it on PC:
Thank you for the help I was on 1803.
I will close as we have many threads on this topic.
