Game pass goals frightfully fun

Hi jigsaw. Since this is not a Rewards program offer, we won't be able to help you. You'll need to reach out to
Microsoft Support.

Prizes for quests are given with the following month. If you don't receive the prizes by the end of November, you'll want to post in the sales and promotions forum for assistance.

I have sent you an Xbox Live message to your
Xbox Live inbox with further information.

Thanks for posting!

As far as I'm aware, the Game Pass Quests are accessed through an app called the "Game Pass Lounge", which still is not available in the UK store (I am also in the UK). Until the Lounge app is made available to the UK, we won't be able to see the quests.
That page in your screenshot is where the option should be to download the app.

Hopefully someone will be able to correct me if I'm wrong, otherwise it's just a waiting game for now, which sucks a bit since I think this is the first month the Game Pass Quests are open to the UK, and we haven't been given the means to know about them.

"Xbox Game Pass Goals is a fun way to get rewarded for being a member. Each month, a new Goal is posted in the Xbox Game Pass Lounge and everyone who completes their Goal is guaranteed to win a prize."

"There is no need to register or sign-up for Game Pass Goals—just navigate to the Xbox Game Pass Lounge to check out your Goal for the month."

"Where do I find my Goals?
Your monthly Goal will be located in the Featured channel of Xbox Game Pass."

Xbox is tracking the Game Pass Goals activities and will reward you if your Goal is competed.
