I got 14 day free free membership but it's not working

Hi there.

You'll still see the option to purchase Xbox Game Pass because as you mentioned you're using a trial and not a paid subscription. The most important thing is whether or not you can access Xbox Game Pass games as part of your trial.

When you go to My Games & Apps>Memberships>Xbox Game Pass, are you able to launch the Game Pass menus and install/play Game Pass titles?

I am assuming the 14 days of gold is a free trial as microsoft do not sell 14 day gold memberships.. Free trials do not give you access to all the gold features. This is meant to be used to test the xbox live features. If you want access to gold exclusive
demos and access apps that require gold membership you will need to purchase a proper gold membership.

What was the period of the subscription you got ? Are you sure that it's not the 14-day free trial ? because if it is so, then yes, you do have to renew your Game Pass membership.

i have 14 days free membership due to my new x box one s. The free games for xbox one i could add for free without problems. Only this game i cant add to my account.

Well did you buy an gold membership or use a 14 day trial? Because you are Currently a free account if this js the account in question

If you used a trial its simple buy an membership

14 day or 48 hour trials are just that trials

They dont give you actual gold and only work with limitations usually non ranked matches in the gsmes they were given in
