Why can't I purchase Fortnite crew from the tab on Fortnite?

Hi Stanley, my name is Rodrigo. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

I am sorry to hear that.

Please, can you give us more details?

Are you playing on an Xbox Console or PC?

If you are on an Xbox Console, please, try power cycling the console.

To do it, follow these steps:

Turn off your console by pressing the Xbox button on the front of the console for about 10 seconds, until it shuts down completely.

Unplug the console's power cable. Wait 60 seconds.

Important Be sure to wait at least 60 seconds. This step resets the power supply.

Plug the console power cable back in.

Press the Xbox button on your console to turn it on.

Hello,

Thank you for posting in the Microsoft Community.

You can subscribe to Fortnite crew inside Fortnite from either the item shop or battle pass tab.

Your subscription is associated with the platform on which you purchased it (your “primary platform”) until it is cancelled. the Fortnite crew subscription is not transferable between platforms.

To claim the current month’s crew pack, you may need to log in from your primary platform if it has been more than 30 days since your last login from that platform. assuming you’ve done this, you’ll receive the crew pack items automatically as long as you’re an active subscriber.

Be sure to choose the platform (e.g., playstation, xbox, nintendo switch) you purchase your subscription on carefully. you’ll be able to access the crew pack items you receive from the subscription across different platforms, but the v-bucks you receive may not be redeemable on other platforms.

Do you know if this is happening only with fortnite crew subscription?

Are you able to test with another in-game purchase or with a completely game or store item?

Another option could be temporarily sign in fortnite on PC or a different device and purchase the subscription from there
