In the new Xbox Game Pass Beta app, the tasks section is missing, letting you only see the...

I haven't looked on the console, but I have the Game Pass and Game Pass (Beta) app on Android and I'm seeing that section still in both, fwiw.

Under the "Game Pass" section in the Xbox (beta) app shows all available games to download and play.

Xbox Game Pass Ultimate member, you can find your perks on your console within the Xbox Game Pass tab, in the new Xbox (beta) app on Windows
10 PC, or within the Xbox Game Pass mobile app. And as Zenosos said Pso2 is Na and Canada only

To access Xbox Game Pass Ultimate on your PC, you will need to install the Xbox (Beta) app from the Microsoft Store. Once you have installed the app, sign in with the Microsoft account that you used to purchase your Xbox Game Pass Ultimate subscription.

If you have already installed the Xbox (Beta) app and are still having trouble accessing your Xbox Game Pass Ultimate subscription, there are a few things you can try:

1. Make sure you are signed in to the Xbox (Beta) app with the correct Microsoft account.
   
2. Check your subscription status by going to the Account tab in the app and looking for the Xbox Game Pass Ultimate section. If your subscription is active, it should show the expiration date.
   
3. Try restarting the Xbox (Beta) app and/or your PC.
   
4. Make sure your PC meets the minimum system requirements for the games you are trying to play.
   
5. If you continue to have problems, you can try contacting Microsoft support
   

I hope this helps! Let me know if you have any other questions.

At the moment you don't need the Beta Key anymore to access the beta.

To download the beta, sign in to your Xbox One and head to the “New Game Demos” section of the Game Store and it will appear there. You can also say “Xbox Bing” then “Show me game demos”. Also, in some Xbox Live regions you’ll see a “Join The Titanfall
Beta” link on the home page of Xbox One, next to My Game and Apps.
