I have, according to epic games, added a v bucks card to my son’s Fortnite profile however...

You need to make sure the fortnite profile from epic games is connected to properly to xbox live. Say if your son by accident signed out and then created another fortnite profile , the v-bucks will go to the account previously connected to xbox live.

Please log in to your son's epic games account and under connections, acounts, you should see xbox is connected. If it is not than the v-bucks went to another account, and you will need to try to recover that account.

Hi Nisargbediya,

Thank you for posting on the Xbox forums.

Unfortunately, V-bucks purchased through the Microsoft Store are for the Xbox One only and per the

Fortnite FAQ on Epic Games website, "Q: Are my V-Bucks bound to the platform I purchase them on?

A: Purchased V-Bucks are shared between PC and mobile if you've linked your account with your Epic ID. However, V-Bucks purchased on PlayStation 4, Xbox One, or Switch are not shared between other platforms.

Any content you buy with V-Bucks will be available on any linked Fortnite accounts no matter which platform you buy the content on."

Basically only V-bucks that you buy through Epic's Store on PC or mobile are shared, but V-bucks purchased on consoles can only be used on consoles. You can however buy a skin using those V-bucks on Xbox and if your Epic account is linked to both Xbox and
your mobile device, then the skin would be shared across all platforms, just not the V-bucks.

Hi schcyber,

Directly quoted from
Epic Games FAQ on Fortnite:

"Q: Are my V-bucks bound to the platform I purchase them on?

A: Purchased V-Bucks are shared between all supported platforms if you’ve linked your account with your Epic ID. Any content you buy with V-Bucks will be available on any linked Fortnite accounts as well."

Therefore, if you correctly have your Microsoft account that made the purchase linked with your Epic ID, the V-bucks should appear on PC. If they don't then try re-installing the game. If you still cannot find the V-bucks, you will need to contact

Epic Games Support.

Hello Hollie,my name is Marvina, I will be happy to help you.

I'm so sorry for what you're going through, here are some things your friend can try to fix Fortnite V-Bucks not showing up on their V-Bucks card:

Make sure the V-Bucks card is valid.

You can check the validity of the card on the Epic Games website.

Make sure you have entered the code correctly.

You can check the code on the Epic Games website or in the Fortnite app.

Make sure your console is connected to the Internet. V-Bucks must be redeemed online.

Restart your console. Sometimes a simple restart can fix the problem.

Sign back into your Epic Games account.

If you're signed in to your Epic Games account on another console, try signing in on your home console.

Update the game. If an update is available for the game, install it.

Here are some specific steps your friend can take to try to redeem their V-Bucks card:

Sign in to your Epic Games account on the Fortnite website or app.

Click "V-Bucks."

Click "Redeem Code."

Enter the code for your V-Bucks card.

Click "Redeem."

If the code is valid, the V-Bucks should appear in your Epic Games account within a few minutes.

If it's been more than 24 hours and the V-Bucks still haven't appeared, your friend can contact Epic Games support for help.

Apologies, according to
this link Epic changed how purchased Vbucks work over cross platforms.

"Why don't all of my V-Bucks transfer across platforms?

V-Bucks purchased on Nintendo Switch and PlayStation 4 are only available on the platform they are purchased on. All other V-Bucks, are available across platform."

I would suggest you
contact Epic Games and confirm this is correct before purchasing any Vbucks you want to transfer between platforms.
