Sometimes, Launching the game fixes this issue

Hi iceDovah4502

For game add-ons and other DLC, the first place to check is in your games and apps. In your games list, focus on a game, press the Menu button  on your controller, and then select Manage
game & add-ons.

Some add-ons are accessed in the game rather than installed separately. Any installable add-ons or DLC not yet installed will appear under Ready to install.

Here’s where to check for add-ons inside the games they go with:

• On the game’s title screen, look for something like “My content.”
• You might need to open a message in a game to get your add-ons. Check for “My Messages” or a related area.
• Some add-ons are found only while playing the game itself. This can be true for items such as V-Bucks or clothing. In Sea of Thieves, for example, you need to start a quest, board your ship, and either visit the in-game store or open inventory chests.
• Accessing add-ons might require you to progress to a certain point in a game. For example, Destiny 2: Forsaken uses game levels to gate the use of certain expansion packs. In Forza Horizon 3, you need to drive to a specific location to start using
  the Hot Wheels expansion pack.

Not seeing your add-on in Ready to install? Sign in to My Games on Xbox.com with the Microsoft account you used to purchase the DLC to see what
add-ons are available. If it’s not on that list, it’s not associated with that account.

If you bought in-game currency such as V-Bucks or FIFA points and you’re not seeing them in the game, confirm your completed purchase by signing in to your Order history.

If you see your in-game currency in your purchase history, try quitting and relaunching the game:

1. Press the Xbox button  to open the guide.
2. Focus on the game, press the Menu button , and then choose Quit.
3. Relaunch the game and check your in-game wallet.

If it’s been 24 hours since you’ve done the above and you’re still not seeing your in-game currency:

• For games published by Microsoft, contact Microsoft support.
• For other games, contact the game publisher. Here’s a list of major publishers and their websites.
