Special-currency purchase fails when the player is not authorized through the Game Hub

If a player has enough special currency on their balance but gets an error when trying to buy an item, first check how the player was authorized.

Cause

This can happen when the player session was started by entering a Player ID directly instead of authorizing through the Game Hub authentication flow.

Resolution

• Authorize the player through the Game Hub.
• Do not use direct Player ID entry as a substitute for the normal Hub authorization flow when testing this purchase scenario.

Expected outcome

After the player is authorized through the Game Hub, purchases for items priced in special currency should work as expected.

Additional note

If the product currently shows a generic or unclear error in this case, the error text should be improved so it explains that the issue is caused by the authorization method.
