If you purchased tokens on PlayStation, you must spend those tokens on PlayStation due to Sony policies.

For example, if you currently have 500 tokens and you purchase 2,500 tokens on PlayStation and then switch to play Rec Room on another platform, your total token count will still display as 500 when playing on a non PlayStation platform. However, if you go back to play on PlayStation, the game should report your token count as 3,000 tokens. 

The same is true in reverse. If you purchase tokens on another platform that is not on PlayStation, you will not be able to spend those tokens on your PlayStation device. 

The easiest workaround is to spend those tokens on in-game items. You are then able to use the items purchased with those tokens on any platform, as there are no platform restrictions on the items themselves.
