Rocket league xbox customization pack not working

I'm sorry to hear that you didn't receive the Rocket League gear after claiming all three items included in the Gilded Hunter pack. Here are a few steps you can take to try to resolve this issue:

1. Make sure that you have linked your Xbox and Epic accounts correctly. You can check this by logging in to both accounts separately and making sure that they are connected on the Epic Games website.

2. Try restarting your Xbox Series S console and launching Rocket League again to see if the content appears.

3. If you still don't see the Rocket League gear, contact Xbox or Epic Games customer support for assistance. They may be able to help you troubleshoot the issue or provide you with the missing content.

Thank you, but let's assume I buy another copy of Rocket League, but not another Xbox Live subscription. When he signs in as himself on my xbox, he will be able to play his copy of Rocket League but how will Xbox Live work?

Hi!

It's the original version of xbox one, 500go I think, bought it in a pack with fifa 16.

In french the message is "synchronisation des données pour Rocket League...", something like "synchronization of datas for Rocket League..." (or any other game).

Now this problem stopped though but sometimes I still can't connect to xbox live and play the games I bought online.

Thanks for your answer

Wait wait...

Rocket League is going free to play on all platforms...

Does this mean when Rocket League is removed from the game pass, I will have my xbox rocket league account the same, or will i need to reinstall it...

And if it is free to play can my friends who dont have rocket league start to play it by downloading it on the MS store?

Many thanks...
