Why aren't all of my Credits shared across linked accounts in Rocket League?

In Rocket League, Credits are treated differently depending on how they were obtained:

Purchased Credits are only available on the platform where you bought them. They cannot be transferred to another platform.
Credits earned from Rocket Pass are shared across all platforms linked to your Epic Games account.

This means your Credit balance may look different depending on which platform you are on.

Example 1: 1,000 Credits purchased on Epic Games Store
- Epic Games Store will display 1,000 Credits available
- Xbox will display 0 Credits available
Example 2: 1,000 Credits purchased on Xbox
- Xbox will display 1,000 Credits available
- Epic Games Store will display 0 Credits available
Example 3: 500 Credits earned from Rocket Pass
- All linked platforms will display 500 Credits available

If you purchased a bundle that included Credits, those Credits are also only available on the platform where the bundle was purchased.

To use your purchased Credits, launch Rocket League on the platform where you originally bought them.
Items you purchase with Credits are shared across all your linked platforms, even though the Credits themselves are not.

If your Credits are missing entirely and this does not explain your situation, refer to Why am I missing inventory or progress across my accounts in Rocket League?
